Thank you for your response. I don't take any caffeine. The only "stimulants" I take are cinnamon and garlic. I am glad to know that your heart palpitations went away, and I hope that parasites are the cause of mine, too. I had a surprising experience today, where I had to call my grandmother to pick me up at the grocery store because I suddenly felt too faint to drive home. This coincided with increased heart palpitations. I wish I could be certain it was parasites, and then I would have no problem staying on my limited diet and even feeling faint and getting the palpitations if I knew I was on my way to better health. It is just difficult to be sure when such symptoms arise whether it is the cleansing process or a signal from my body to do something differently. I guess I will try eating a little more tomorrow and seeing if I feel any better.
