I was at 300mg/day for a few years. Slowly went down & have been taking 100mg/day for the past 2 weeks. I'm still having a lot of withdrawal being on the 100. A few hours before my dose my head starts feeling very strange. Quite hard to explain, I have dizziness/vertigo, nasuea, extreme fatigue, and the feeling of being unstable on my feet or even while sitting. I'm not comfortable driving due to not feeling fully alert & moving my head makes it worse. I've had this withdrawal feeling before but never lasted this long, any input would be helpful! Thanks!
