Since 95% of people diagnosed with ADD (attention deficit disorder) and ADHD (attention deficient and hyperactivity disorder) don't actually have these psychiatric problems, what makes you think you do?
---------------------
umm.... like 5-9 hours of sleep, 4 hours on my phone each day plus some time on computer, i binge-eat everything, i drink like 4 cups of water a day and a lot of tea. also, not that you care but, if you want to know what my brain is like, turn on 3 songs at once, and try to focus on just one.
Reduce your tea.
Some types of tea can calm the mind and others can stimulate it.
Reduce your screen time.
Excessive screen time (particularly before bed), can stimulate the brain and stop you sleeping properly, and in the long run it can mess with your head.
Reduce sugar and flour in your diet.
Sugar and flour cause your blood sugar to go up and are regularly linked to hyperactivity. You want to eat a balanced diet with meat and vegetables, fruits and a small amount of grains (corn, rice, wheat).
Remove artificial colours, flavors & sweeteners from your diet.
There have been hundreds of scientific studies that have shown a link between artificial colours, flavors & sweeteners and the appearance of ADD and ADHD symptoms in people, particularly younger people (under 21). Removing these things from the diet of people diagnosed with ADD and ADHD fixed 99% of cases and the child no longer had those symptoms.
Exercise for a few hours each day.
Exercise physically tires out the body so you sleep better. But it also circulates the blood around the body and stimulates various chemicals in our body, and these help stop our brain going off into la la land.
Don't use electronic devices for 3 hours before bed.
Electronic devices like computers, internet, mobile phones, all stimulate the brain and cause it to race. Having a break from these devices helps the mind settle down and lets you rest more effectively rather than thinking about whatever you did online. If possible, try to not to use mobile devices at all on several days each week.
Spend time outside in the sun (use sunscreen when necessary).
Humans evolved outside. We need sunlight to set our body clock so we wake up and go to bed at certain times. We also need blue light form sunlight to help our brains work normally. If you live in a cold climate or don't go outside much, have a daylight globe (with lots of blue light) on during the day and have a warm globe (yellow light) at night.
Get at least 8-9 hours of sleep per night.
Lack of sleep causes you to go nuts. Young people need at least 8 hours every night and most teenagers need 9-10 hours per night. Lack of sleep stops the brain from being able to process everything it has taken in that day. Lack of sleep also screws up your body and puts immense pressure on your heart and other organs.
Try to go to bed at the same time every night.
Drink about 2.5 litres of non alcoholic and non caffeinated liquid per day. No fizzy drink, no coffer, no alcohol, minimal tea (especially tea that stimulates the mind).
Drink filtered water, milk, fruit juice that is free of sugar and artificial sweetener, vegetable juice that is free of sugar or artificial sweetener.
