Or baclofen (5mg or 10mg before bed), similar but a bit different (and not scheduled if you are in the US). Either should also help keep you asleep, at least for the first night or two (like almost anything that affects sleep :(). Both affect GABA-B receptors, and I think alcohol affects both main types. Although, if your issue is similar to my similar issue (usually mild sometimes during the day but worst before bed, although not enough to keep me awake ever) the baclofen (or sodium oxybate) might even possibly make them worse (seems possible in my case, although I'm not sure it is all that likely that it does).

Another one you might not have considered is rosmarinic acid ("rosemary extract" or "lemon balm extract" or just a strong lemon balm tea). This reduces the metabolism of GABA and in my experience had a distinct but fairly mild effect on sleep that lasted a month or two of continuous use (unusually) but then took over a year to have any obvious effect again (possibly even longer, I haven't tried it much since and I can't remember if it ever really helped again). Unfortunately, I don't remember it having much effect on my movement issues but since alcohol and benzos affect your issue it might be worth a try rather than those if it happens again (hopefully not!). I was using 200mg rosemary extract standardized at 20% rosmarinic acid (from a no longer available source). I don't know if the chamomile does something similar, in which case it likely wouldn't help you due to the tolerance.
