Hi,
Yes, it is very frustrating! I also tried what you have tried with supplements and tonic water. Some days are worse than others but I do know it always is better when I am not thinking of it, which is easier said than done. I am going to get a 2nd opinion, but it sounds like time and reduced stress/anxiety is really the only treatment. My neuromuscular specialist said because it is benign, there is limited research and not very many treatment options. If I find anything that helps, I will reach out!
