I can't imagine that being off Klonopin for a few years had anything to do with a TIA or Seizure etc. No way they could be related after that much time.

I cannot emphasize the word "slow" enough. We know that w/d can cause a heart attack. However, you wean, be sure to do it as slowly as you can. I chose water titration. I found it to be agonizing cutting the pill. I was on 1 mg of Xanax forever. I had to switch to Klonopin, 1 mg., and then I had to cut it in half and took the .50 for a month (agony.) I started the water titration on the other .50 and that lasted approximately six months. The w/d did continue fairly intense with the worst one being on New Years Eve (my last taper.) I thought I wasn't going to see daylight, but I did (God is Good.) In hindsight, I realize that I should have titrated much slower. Maybe, I should have quartered the pill and then started the water titration. On another note, if you decide to do it that way and you have to get through something traumatic in your life, you can "hold." In other words, titrate the same amount, until you get through the traumatic event and then resume the process. Everyone has their own way of handling it and that was the way that worked for me. The Ashton Manual and YouTube can help you with it, as well.
