From reading almost every post that i've found it seems gastritis doesn't heal? My GI doctor said maybe 3 months but that's sum BS after reading on this site it seems that some people have had it for years. Is this the case it takes forever for the stomach to heal? How come? I've been doing this bland food diet and only drinking water for a while now but it doesn't seem to be getting better. I got my gastritis due to taking too much medication for two days tylenol #3 to be exact. I should be sleeping i got a doctors apt in the morning but i can't im nervous about that too.
