My problem isn't an every day occurrence, but when it does come on, it is mostly at night when I'm laying down to rest. It almost seems to start when my Digestive system reaches a point of distress, either from something I may have eaten, or possibly from taking too much to combat my gut issues like Probiotics, magnesium, digestive Enzymes, lemon water, or Peppermint oil. It's truly hard to tell, but my gut goes into such distress that my body breaks out into tremors sometimes lasting about 30 minutes. Doesn't help that I panic, but my wife is a godsend and gently rubs my belly in a form that actually brings relief and gets my mind off things. The tremors are specifically in my lower abdomen and from there radiate to my legs. I can visually see my thighs twitching from the tremors. I'm going in for a colonoscopy on December 9th to rule that out, but have to admit this is concerning. I'm very focused at the moment on healing my gut, cause I feel there is truly a connection between gut health and so many diseases and symptoms these days.
