hi, lately i havn't refilled my strattera and i am currently awaiting a refill however, one thing i noticed when i'm not on my daily dose is that i seem to have characteristics of a fever. i feel really hot inside and i feel a tad mentally drained. has anyone else experienced this?

It's not easy when going off a medication (I know that's not your case). I would wait it out a week and see what happens. If the feeling is still there, see your doctor.
