Today is the 4th full day of taking generic Keppra and damn...The 2nd day was horrible I felt like I was drunk all day, went to work and it started turning into the way too drunk "spinning" feeling and couldn't concentrate on anything I was trying to do, then I had to leave a few hours early because I got so tired I was ready to sit down on a box or anything and just pass out. I got to bed about 8pm and didn't wake up or move at all until 10am, it knocked me out 14 hrs solid. Yesterday and today I felt fine, "sober", I can concentrate and think clearly, dealt with work fine, it's definitely still affecting my energy but not anything like the 2nd day, I've taken it with and without food, so far it hasn't bothered my stomach at all, a few very small headaches that haven't been much of a bother but overall I generally feel good. I've noticed a few bitchy moments at work with some people when I've said something I normally wouldn't but I've caught myself from saying anything out of line. It still all depends how well this stuff works for me but I don't think I'll have a problem with it if it gets things stopped.
