Yeah i get this too. As a collector of militaria, i get really excited when i find new flea markets (You will find alot of militaria if you go to a lot of flea markets). As soon as i find something i want, i get acid reflux because of the excitement. The problem with it though is that when i get a really bad acid reflux during these moments, loss of interest is something that follows as a symptom which makes me just want to stand still and not do anything which is annoying.
