I'm NOT a benzo person and hate feeling drowsy in general, but there's something very euphoric about etiz mixed with stimulants like 4-FA. It sent me into a hypomania state, which I've never experienced. I used it almost daily since March, with my highest doses ranging 6-7 mg per night. I'm now in the process of quitting and it's reallllllly sucky. Worst depression I've ever felt along with sweaty, nightmare-filled sleep and a constant urge to move (akathisia?). Opiate withdrawal has nothing on this.
My reasons for quitting are weight gain and hormonal issues. I assume it's the prolactin-increasing effects of etiz but don't really understand all that. What I do know is it's in the same class (thienodiazepines) as the antipsychotic Zyprexa, which was pulled from the market for causing diabetes. They may not be all that similar structurally, but I'm seeing too many metabolic effects to justify using this any longer. My experience with antipsychotics was very similar to this: rapid weight gain, overwhelming craving for carbohydrates & general weirdness with my moods. (Etiz seems like it falls somewhere between a benzodiazepine and an antipsychotic).
Anyway, just wanted to share my experience. Etiz is great for sleep or anxiety but should not be used regularly. I can see a lot of good people getting into trouble since it's so cheap/easy to obtain.
