Dr. Anthony Vertino answered

Specializes in Clinical Psychology

Crash: It's not uncommon to crash after too much caffeine. Your brain eventually metabolizes all the caffeine and now needs to rest. Also, your heart rate and BP have been elevated (usually not much, but to some extent) and your body perceives this as stress and a reason for rest.

No H-Pylori... Very minor Focal Intestinal Metaplasia... How can I reverse the very very early stages of this? I do eat a fair amount of sodium in foods. I could cut down on that. I also drink a lot of soda and caffeine.
