I'm so sorry [...], your symptom description brings back painful memories for me, what your doctor is doing to you is criminal, he has no idea the pain he's causing you. I believe the taper plan he's laid out for you will do you more harm than good, taking those doses every few days on top of the rapid taper he's demanded will do nothing to stop your pain, it will only delay the inevitable and not provide any relief.
Do you have a history of seizures, they're rare but can happen so when you ask if it's safe, I can't answer that. But if you're asking if you might as well quit cold turkey then that's certainly an option, your taper has pretty much been a cold turkey.
My first three weeks were the worst but things began to improve, I was able to function. If you're determined to do this especially if you don't have the support of your doctor and as long as you understand that recovery is going to take months if not years then you're fully informed and can make your decision.
Do you have family around to keep an eye on you?
