I'm not sure what the long term effects of chronic melatonin supplementation are, but I'll find out eventually. I've been taking between 3-6mg of melatonin every night for the past few years (2011?) It's almost required. Without it my sleep cycle seems fine at first, but then gets out of whack as I can't seem to keep a circadian rhythm in line with the rest of society / the earth's rotation.
On the opposite end of the spectrum, I can't function mentally without caffeine. I tried going off caffeine a few times, and while the withdrawal effects were horrible, they eventually passed and everything felt great except my ability to concentrate on anything. Sadly I can't afford to see a doctor for my ADHD meds. While caffeine helps, it still leaves much to be desired.
Exercise helps immensely, both in terms of sleep and ability to concentrate, but at some point I injured my upper back (rhomboids and rotator cuff muscles), so I can't get the same level of exercise I had before.
