I started taking anti-inflammatories for a back injury that has gotten progressively worse over the years.. Apparently they make your system produce more acid. Not to mention I was trying to be good and up my water intake but neglected to remember lemons are highly acidic and should not have added then to my water, Esp after 6pm ... Needless to say, I won't be doing that again and have started taking prevacid... Thanks ladies! Xoxo
