I didn't get any significant withdrawal effects from venlafaxine, even when I was on the top dose. I think I was lucky though - as others have said some people get quite badly affected by withdrawal - I guess my point is it does vary between individuals, so while it's worth being careful and aware of the scary stories, there is a chance that it won't be as bad as people prepare you for. In terms of sleeping meds, different ones do have different characteristics - how long they stay in your system for, interactions, slightly different side effects, how quickly you can become tolerant to them etc etc. If there is anything you really need from a sleeping med - ie maybe you definitely want it to be short acting and not hanging about in your system the next day, or you want it to be available in tablet sizes that allow a graduated dose - a small dose first then another small dose later if the first dose didn't work, or if there is one you really don't want, then if you can tell the GP/psych that this sort of information may help identify the one best for your situation? Seems a big ask to just get you to pick one. Could you try picking what you need from it then seeing if they can get the nearest fit meds wise, if that makes any sense? Good luck.
