I was taking 25mg twice a day for a week. My doctor told me to stop because I ended up suffering from horrible side effects (sickness, insomnia, deep depression, suicidal thoughts). I already have severe problems with depression, so my mood has crashed really badly. I stopped taking the pills about a week ago now, and I still feel pretty bad. I haven't returned back to normal at all. I just started taking fluoxetine (Prozac) as well, could that prolong the effects of topiramate? I just want to know when I can expect to feel better?
