I'm taking a 37.5 mg pill twice a day and I feel like *****. I know this will pass but god this is a nightmare. Stayed up all night last night feeling wired, nauseated and overly anxious. Tried to go running today but only could make it just over a mile before feeling like I was going to puke or pass out. At work I was panicky, dizzy, light headed and miserable. Also, I have barely eaten a thing -- zero appetite. God bless western medicine!
