You should definitely second guess your doctor, or get a second opinion[1]. I mean everyone knows you should NEVER abruptly stop benzodiazepines due to lethal/fatal withdrawal symptoms, right? Guess what? Most of the psychiatrists I have encountered do not give a damn. It is coming from both first-hand and second-hand experiences. So yeah, you are right to second guess. Were it up to my doctors, I would have been long dead. And because I was not in the right state to second guess my doctor, I am forever left with immobility issues. I should have gotten a week long corticosteroid therapy for MS relapse. I did not, because the doctor did not give a fuck, and I was too stupid to NOT second guess. Unfortunately they do not give a damn about you here, but you should. FWIW everything I have said do not require me to have a PhD or Dr. next to my name. It is on Wikipedia, books on psychiatry, pharmacology, and so forth. It is "common knowledge" in the field that you are supposed to taper off these medications gradually, never abruptly.

[1] You would never guess the amount of times I have encountered doctors questioning the practices of another doctor. :P It happened so many times...
