Fascinating.
I have a very fine tremor which responds to alcohol.
I never knew mine responded to alcohol until the MDs told me. I don't drink much alcohol. I did test their hypothesis and they are correct, the tremor lets up with alcohol intake. However, I am not drawn to alcohol and am truly lucky, as I don't need alcohol interacting with my meds.

I just asked my husband about bitter beer/ales. He agrees with Dave on the IPAs being most bitter. However, around here, the IPAs are also very popular.

I think some stouts are bitter. Yet, I must admit to ignorance.

Just curious, and I hope you don't mind my asking -- does anything else also give you relief? I have myoclonus, myotonias, tremors and ... like to learn whatever I can when the opportunity presents. (I find sodium channel blockers the most helpful to me -- I am trying a somewhat new med, Aptiom, in the same drug class.)

Cheers!
