I take 300mg Dilantin at night, Lamictal, Leviteracitam 500mg am/pm of each. I also smoke Cannabis during the day. I told my Neurologist that I did so,to be honest. He didn't condone it, but I wanted to let him know just incase it was possible to adjust my AED'S. I have been doing so now for over 25 years. Siezure free! The only time I have a break thru is when I screw up on my AED'S.
