hi, I started taking this med in nov.2004.I just had a baby and had my tubes tied and never had them befor until then.Since i been on the meds i notice some of the same feeling haven energy,sex drives like crazy.Feeling like i'm drunk and stoned all the time. My doctor said that was fine until my body gets use to me using it.Well how long does it take to get use to something like that.I take 300 mg myself and also notice it helps me out in alot of way then my seizure.
