OK, so I finally figured out what's going on with me, why my POTS has returned. I have been having trouble with swallowing, getting too full fast, reflux, etc. These are the same symptoms I had before I had my brain injury surgery so I equated it with my brain injury. After surgery I was able to eat so much better. Now, after 6 years, I'm having my stomach issues back, as well as the POTS. So, my gastro doctor recommended that I get a stomach emptying test. It showed that I still had 64% of my food in my stomach at that point. So, after looking up the gastroparesis diet, and them mentioning softer pureed foods, etc. I did that so a week, and for a whole week, I was constipated. Ugh! However, I did have a respite from my tachycardia. Tonight, I couldn't stand the constipation any longer, so I took 2 cans of prune juice, it did the trick, I cleaned out, but I also noticed my tachycardia returned and dizziness (that had been gone too). It's so frustrating and not sure what to do, because softer foods helped me feel better, not feeling as full, helped the tachycardia, etc. But it made me constipated, but if I eat the more normal foods, I feel full, feel tachy after I eat. Most likely the constipation was from the liquid diet and lack of fiber. There has to be a happy medium in there somewhere. If anyone knows, please share it with me. Thanks.
