I made an account just to comment on this thread. I ordered 100 etizest-MD tabs thinking that I would use them for occasional stressful days, flying, social anxiety, etc. Took one the first night and thought, "Oh, not bad. Very mild - like benadryl." Took another 1 mg the next day and experienced a nice calm feeling. After it wore off, I decided I wanted the feeling to last, so I took another. Within a matter of days I was a daily 2-4 mg user. I had been hooked on temazepam several years ago, so i knew how addictive benzos could be, but I had read that etizolam had a very low tolerance buildup and low withdrawal risk. WRONG. I immediately tried to start tapering down to half a tab every 5 hours. The rebound anxiety came promptly at 4 hours every time. The best I could do was around 6 hours and it was very unpleasant - heart palpitations, shaky hands, pit-of-stomach feeling, the works. I considered ordering 100 more and trying to taper over a longer period of time but then wisely took the advice of other former etiz users on reddit and went to my doc to get a long-acting benzo. So now I've been tapering on 2 mg of Klonopin a day for the past 2 weeks. I think tomorrow she'll put me down to 1 or 1.5 (I hope the latter). The rebound anxiety every 4 hours is mostly gone, but I still don't feel "normal" and the Klonopin just sort of takes the edge off.
So, the short version is this: If you have the slightest bit of addictive personality and like the "chill" feeling, STAY FAR AWAY FROM ETIZOLAM.
