For example, many people with MS get fatigue so badly that they can't manage to do anything during the day, though sometimes it happens suddenly without reason. Modafinil and the like are the mechanisms for overcoming this. Side effects are much more tolerable than suddenly having to lay down and sleep.
Wait what?
Anyway, good for OP; if a chemical substance was causing them a problem, getting off it is the right thing to do.
BTW. it seems like adrafinil (much cheaper, though apperently little less safe modafinil form) sources are drying up.
I use Modafinil _responsibly_ (I like to think) and for me that means 50 mg, taken early in the morning, only on days that I might need the boost (bad night's sleep, busy day, etc).
