I'm in the same boat. I've had acid reflux for years and lived on pepcid. Before I got a prescription, I was up to 4 over the counter pepcids a day. I used to think it was red meat that was causing me a lot of problems like heartburn and constipation, but ever since I started on Atkins, I've only had one heartburn and that was when I ate cucumbers with seeds. I know it sounds gross, but I used to go without pooping for days, sometimes up to a week. I was in such pain! 3 weeks into Atkins, I'm going every morning like clockwork.
