Well, I've been taking 1000mg of Keppra three times a day for about 6 weeks. When my dosage was 1500mg twice daily I was miserable and most people were afraid of me and my crankiness. It seems to have helped. It's still not perfect but there is improvement, also my husband has been on strike for 5 weeks so there are other stresses on in my life...if he ever gets back to work, the weather improves, whatever, it will be just fine! Keep your fingers crossed!!
