I pray you are okay. I too suffered from the same but have found relief with a combination of slippery elm, marshmallow root, garlic in tablet form, oil of oregano tablets and a complex of injected b vitamins seems to curb the internal quivering. I was diagnosed with SIBO (small intestine bacterial overgrowth). With additional traditional antibiotics, my condition is diagnosed in remission. Many teas helped me over these last few years. Mint tea as well clove.

Hope and pray you have found the same or this information helps you in some way
