On Keppra, Zonagran, Onfi, Zoloft and Melatonin

I've had epilepsy for 22 years now since I was 10. Ever since the first day I had my first medication I've had nothing but medication problems. My first medication was Depakote. When I was put on it, I gained over 100pds. in a month and a half. Which made me 288pds at the time cause I was tall and skinny at first. About 11 or 12 years later I was put on Zonagran and it finally made me lose 70pds of the 288pds. But since I lost so much weight so fast all I have is extra skin that I can't get rid of no matter how much I exercise and work out. I've been on Keppra for more years than I can remember and Keppra mostly seems fine but I think it's the one that takes away my muscle mass cause I'm on 5000mg a day. Also Keppra could be the one medication that's causing me to have a cold sore pop up in my mouth all day about an hour after I take it unless it is the Onfi that's causing that since I take'em both at once. Also I have terrible trouble going to the bathroom having a bowel movement. I eat healthy and still whenever I take a crap, it feels like I'm giving birth. lol. I had panic attacks at one time and I learned that Zoloft causes lucid dreams and can even cause panic attacks. But Zoloft is for my depression mostly now. Other side effects I have now or have had for years are Anhidrosis which is where you can't sweat which can easily lead to heat strokes. I have Todd's Paralysis but I don't know if that's a side effect or not. I don't have headaches anymore but I do have body twitches a good amount of the time and body pains shooting through my arms and legs. That's all I'll say for now. They need to get rid of the billion dollar medication companies and just give us the cure for epilepsy as a pill form. But since they put profits over people, it's terrible for us, the cure is too much of a threat to these companies.
