Unless I use medication, I don't ever seem to get tired... day or night. Help! ?

Insomnia. Do you take any supplements besides your meds? How much caffeine do you drink (coffee/tea/cola/energy drinks)? Diazepam normally causes drowsiness, but in some people it causes overstimulation. Overactive thyroid might also cause constant alertness, nervousness, etc. Discuss your problem w/ FP; take along ALL meds for review. May need lab work to determine cause if not over-caffeinating.
