I recommend trying this diet if you have weakness and stability issues. Personally, I think if your issue is tremor only, you may not find this regimen beneficial.
Coconut oil: 6 tbsps per day (or more; adjust to your experience) Recommended: 2 tbsps at each meal and 2 before bed.
Heat 1/3 coffee cup of coconut milk, the variety that contains 6g of sugar, place two tbsp. of coconut oil and after it melts in a moment, you have a tasty drink not unlike hot cocoa.
