Rates of overweight and type 2 diabetes are higher in people with ADHD, and the reasons are not moral ones. A reward system that is under stimulated goes looking, and food answers quickly. Add difficulty noticing when you are full and the pattern more or less builds itself. Knowing its shape lets you change the setup instead of fighting each individual moment: what is in the cupboard, when meals actually happen, what else in the day gives you a genuine lift.

Four cups a day and upwards starts producing insomnia, irritability, tremor, an unsettled stomach and a racing heart, and a few people go sleepy on it rather than alert. In anyone whose sleep is already fragile, the attention lost tomorrow costs more than the alertness bought today. It is a particularly poor swap for a child's medication, since children can end up in withdrawal.

Two things help more often than they get suggested. Cutting caffeine frequently settles symptoms on its own, since it speeds the gut up and raises acid. And there are talking therapies designed specifically for irritable bowel, which work on the stress side rather than the food side. A low FODMAP approach is worth exploring with a dietitian, though it is fiddly and not meant to be permanent.

Use it early in the day and use it consistently, since the timing is part of how it works. It is also worth asking whoever prescribes for you about vitamin D over winter, particularly at high latitude or if you have darker skin. Plan for the season before it arrives rather than after six weeks of wondering what is wrong with you.

The list is usually short and dull: the light on a charger, the pile of unfinished things on the chair, the television, the clock you keep checking. Change one item this week rather than all of them. Doing this before reaching for something to help you sleep is not a lecture about willpower, it is simply cheaper and it lasts longer.

One clinician telling this story about himself had a level that was almost undetectable, and no antidepressant would have raised it, because what was missing was a substance rather than an effect. That does not mean everyone low in vitamin D is low in mood for that reason. It means this is cheap to check and expensive to miss.

Correcting a deficiency usually means a high dose for a defined period and then a steady daily amount, with the level rechecked to see where you have landed. Both halves matter. Buying a stronger tub yourself and hoping is how people end up either still low or taking far too much for far too long.

An untreated thyroid problem also blunts how well antidepressants work, so missing it can mean months on a treatment that was never going to do the job. Treating it sometimes clears the whole presentation. None of this is an argument against treating depression. It is an argument for one blood test before committing to a long course of anything.

The natural reward for walking more is invisible and decades away, which is no use to a brain running on what happens next. A small stake, a streak, a friend expecting a message: each of those moves the reward closer. Keep the stake small enough that losing it stings a little and does not hurt, and change the game when it stops being interesting, because it will.

Write anger into the relapse plan by name, alongside the parties, the old friends and the difficult anniversary. Then when you look at the anger, ask what had been drunk or taken in the days around each flare. Both questions belong on the same page. It is rarely that someone lacked willpower on the day, it is that each half of the loop keeps quietly restocking the other.

Episodes that look random from close up often turn out to have a shape once there is a record of them: a point in a monthly cycle, a change of medication, a course of steroids, the months after an illness. A pattern like that points somewhere practical, which is putting the hard conversations on the easier days rather than trying to be a better person on the difficult ones. Anabolic steroid use has a well known reputation for rage and needs medical help rather than psychological technique.

The lift is real. Heat, clarity, energy, a body that suddenly knows exactly what to do. Take that away and leave a gap where it was, and within a month the gap gets filled by the same thing again. What tends to work better is finding something that offers a version of the lift, hard physical effort, work that fully absorbs you, prayer, so that the anger becomes less necessary rather than only forbidden.

The chemistry gets talked about a great deal and it is the least useful part. What you can act on is the diary: a standing meal with someone, a hand on a shoulder, telling one person something you would normally keep back. Put those in the week rather than waiting until you feel like it, because the feeling usually arrives after the arrangement, not before it.

Loneliness does not make you a poor judge of character on purpose. It just lowers the bar until whoever turns up seems fine. The steadier answer is small and regular: a call every Sunday, one standing thing in the week, so that you are never so hungry that you stop choosing.

None of them are about anger directly, which is the point. Exercise lowers what you are already carrying before the argument starts. A shared meal puts you among people with nothing to settle. Sitting still trains the noticing that everything else depends on. Pick the one you would actually do this week rather than the one that sounds most serious.

Sit down with somebody once a week and eat whatever you were going to eat anyway. That is the whole practice. If you notice yourself reaching for food when what you actually want is company, that is worth saying out loud to a person rather than solving with a second plate.

You do not have to establish which came first. Easing the pressure on your nervous system helps digestion, steadying what you eat helps mood, and either one loosens the loop a little. Pick whichever is more within reach this week rather than waiting until you can do both properly.

This is not about swapping therapy for supplements. It is about not spending a year working on something a blood test could have partly explained. If you have already given the psychological route a fair go and nothing shifts, that is a good moment to ask your doctor what has actually been checked, and to ask for the results rather than just the reassurance.

Symptoms that arrive together are worth asking about together. If reading, mood and stomach all went wrong over the same period, that pattern is information, and it is worth taking to a doctor before it hardens into a set of labels. Testing for coeliac disease has to happen while the person is still eating gluten, so ask before anything gets removed.
