Honestly, the effects you are noticing. (Minus the sleep deprivation) are pretty much how I also felt taking Strattera. Honestly, it might be more the meds rather than the lack of sleep, making you feel that way. If you just started taking it, it has so weird little side effects that seem to go away after a week or two.
For me, not being on the medication made me not able to sleep, and being on it made it easier than ever to just fall asleep when I wanted. Which was something that I was never really able to do before.
But it affects everyone differently, so keep your doctor informed if the sleep issues don’t go away as that is not healthy!
