I have been given the 20mg Ampheta, it says on the bottle take two to three everyday. How do i work out the time inbetween of taking it. What other meds should i space out with it, i take Cymbalta, and Trazadone for sleep. Would it be better to take Melatonin for sleep than the Trazadone? Most of the time it levels me out, but at times i actually feel a little Euthoric as i feel so on top of the world, not hyper, just a good energy, is this normal?
