I've been having trouble taking a deep breath and when i eat i get discomfort in my chest and stomach. does water detox with lemon cucumber work?

See a doc: You have already been diagnosed with heartburn according to your history, and this sounds like gerd. The other thing it could be is a hiatal hernia and this is why you should see your doc. Occasionally a congenital hiatal hernia can cause these symptoms and can be ruled out simply with some imaging. I would not recommend just a detox with lemon and cucumber, although give it a try, then see a doc.
