OrangeK, sounds like fun plans coming up! Didn't you get that feeling in your stomach before a concert and fun weekend you had planned previously? Maybe there's a correlation between making a lot of plans and some anxiety or anticipation about them? You might still consider the magnesium supplement or some dietary changes to manage the feeling in your stomach and physical sensations you get if your doctor says that's ok. I have no idea about your lifestyle and diet but you can try drinking more water, reducing caffeine and alcohol, and eating healthy easy-to-digest foods when your stomach has that feeling but it does sound more connected to your mental state so it's probably just related to the life stress you're experiencing.
