I had been taking strattera for a few weeks only to develop bad muscle pain that felt as though I were continiously being ''frogged'', upper stomach pains and extreme sleepiness. I had also completly lost my appatite,so in order to function I had to go off of it.Even since I have been off of it,I still require ten or more hours of sleep[which I dislike] where previously,I only required four,to six hours of sleep.It's as though the medicine ''reset'' my system somehow.
