... severe heartburn. I always eat very healthy meals. Lately i've been eating smaller portions, eating meals like melon with faye(non fat greek yogurt) and granola. this morning, after eating this specific bowl of food, i felt my energy shift, my head fell into a heavy foggy state, and my upper abdomen immediately bloated with tension and pain. its now 10 hours later, and i still do not feel better. has anyone else experienced this?
