I know a lot of people with FMS also have acid reflux disease (GERD), and I know that for most people, the acid is worst after meals and sometimes when lying down or sleeping. I seem to get it frequently from drinking water! This can be a big problem, since everybody seems to say you should drink a lot of water during the day. I try, but lately even just taking a swallow of water seems to kick up the acid. That makes it very hard for me to drink anywhere near the amount of water I'm supposed to drink. I already try to watch what I eat, and I take Prilosec (and Tums and sometimes generic Zantac 75) to try to control the acid. As I said in another post, my doctor has referred me for an endoscopic exam to rule out Barrett's Esophogus, but I'm just wondering whether anybody else gets "the burn" from just drinking water. --Laura R.M.
