I had been on 50 for years and lately got "lazy". I'm in the middle of the worse anxiety I've had in years. I've been back on solidly for 4 weeks. Doc wants me to wait 4 more for things to get settled. Hope you're hanging in there!
I agree with Suzi. Also, in case you were unaware of this suddenly stopping this type of medication can lead to very serious, and dangerous, "side"-effects, seizure is one of them. Neither quit these medications cold turkey, you need to "taper" off them.
I am not a doctor, but I am sure that you didn't do anything to your brain...however, you are probably giving yourself horrible side effects and then withdrawal....are you under a physicians care? Your doctor should be monitoring you as you go on and/or off. Stay on it! If you want to come off please do it under your doctor's care.
