Your heart is weary of, and irritable over, many hours of adrenaline washed video gaming. If I were a betting man, I'd bet you have gone short on sleep because you simply couldn't bring yourself to leave what seemed like a good game going for you. That's more stress.

My advice is to use what works, and to perhaps consider a change in habits and lifestyle. I'm not a gamer, but I'm a rabbit holer on Youtube who just recently went down a rabbit hole until 0300 hours. Thankfully, I only do that once or twice a year, and don't go until 0200 like I was just three years ago. It's too hard on an aging body.

I, too, get some indigestion now and then after a meal. Either eating too much or the wrong thing, or too much alcohol with a meal, things I stopped doing a few years ago. Red wine is death for me. Bending over to tie shoes after eating is also bad for me. I gained weight over the past 18 months waiting for ablations. Thankfully, the last one 18 weeks ago seems to have 'taken' and I am good and beginning to exercise MODERATELY once again.

Do you want control of yourself, or your predilections to control you? It's that simple.
