I can relate to the problem of trying to figure out what to eat. I have been tracking my food intake for 3 weeks as I think I am showing signs of dairy intolerance. I have also had problems when I was eating pasta all the time. Before I was diagnosed 3 years ago with POTS, I was a vegetarian and lived on pasta dishes (and fish). After POTS I tried to continue eating pasta and EVERY time I did, I became symptomatic within minutes. My doctor said to eat protein at every meal (first)and with pasta only very small portions. That made a big difference! Now, without cheese, I don't really want pasta. It IS frustrating to figure out a good, healthy, POTS-friendly diet but I keep trying. I added chicken and turkey back in my menu (can't handled red meat though) as well as lots of soups high in protein and all types of frozen vegetables which are easy to prepare. I'm am on Florinef also. Often I have to work to keep weight at the level my doctor wants to see me at but what works for me won't for you....pbj sandwiches everyday!
