I tapered down too fast once and OMG...I'll never do it again. Pounding headaches, massive anxiety, panic attacks, delusions, scared, mind racing, crying, curled up in a ball. I quickly started back on it and it subsided. I felt like I was in a wreck. I don't know what that was but it was freaky. The second time I took longer to taper off and it wasn't bad. I started cycling bad so I just went back on it. I've been on it solid since then.
