Does anyone have this or know why I'm having these issues? It feels almost like low sugar but I've checked several times and its fine. Very annoying.

Maybe you are getting a cold?

Could be low blood pressure. Are you keeping your fluids up?

That's what the doc office asked, I can drink 5 to 6 cups a day but struggle with more.

Have you eaten something you shouldn't? Those can also be symptoms of dumping syndrome. That's when you have too much sugar or fat go through your stomach too fast and into your intestines. I had it on Christmas night. I thought I made good choices but because I didn't prepare things, I didn't know how much hidden fat/sugar were in them. It was like a real bad case of food poisoning only without the vomiting. Dizziness, chills, pretty nasty! Hope you feel better!
