ListoR: not really..I have tried many things but only with small success..now I try to do not eat or drink anything with caffeine, taurin and other stimulants - I just try give some rest to me nerves.. I can say its better, I twitch definitely less.PS: Its known fact that coriander is the best natural detoxicant of central nervous system. I have not tried it yet, since I cannot get it fresh...but I think it is really worth.If you know the story of als patient eric who stopped ALS with his own detoxication, you will probably know that he was using coriander too..no matter if this famous story is truth or not, I would like to try coriander..
