I've taken 40mg for 3 yrs. then 60mg for 1 yr. I have new insurance and they won't pay. I had to stop cold turkey and am sick, sick; major brain zaps for a week now, contraction like stomach cramps, crying... took the last 2 days off work. Everything I'm reading only says to take up to 20mg a day. Did my dr over medicate me?I also take trazadone, klonipin, and adderal
