I have just started taking Keppra 500mg two times a day for post concussive headache.

I previously took nortriptline, but it cased me to gain weight (10 lbs in 6 weeks!)

I've taken just one dose of Keppra and it kept me up most of the night with night sweats and a headache at the base of my skull, which I did not have previously.

Now I have both the original headache and the new headache at the base of my skull. Does anyone know if the headaches will cease with additional Keppra? I hope so..I've been on 4 different meds and would really like to have one that works~
