I am (well - used to be) a full time acid reflux VICTIM. I was on omprazole for 5 years and then zantac. When I decided to get preggers - I refused to take more meds and tried - Apple Cider Vinegar, D-limonene, cabbage juice, baking soda, tums and many others. I ended up going 3 weeks without eating anything at all.. Even water gave me terrible pain.
I actually read about Chia seeds on mothering.com. I wish I had read about them sooner. They are so safe that most midwives recommend them as a supplement because they have folic acid, vitamin A, omega 3 and omega 6 and fiber. When I first started taking them in September - I took 4-5 teaspoons a day in water - they make a gel when wet. I couldn't take my prenatal vitamins to South Africa in November (while TTC'ing) - but my friend found a $10 bag of seeds there and by then I was down to one tablespoon of dry seeds chased with water or juice. NOW I only take one teaspoon every 2-3 days. I had suffered for so long and now I don''t have ANY reflux. As nauseous as I have been - I'm pretty sure if it weren't for the chia seeds - I would have horrible indigestion. I had it with my first pregnancy and back then I was still taking omperazole - which they said was safe.. but I miscarried - so maybe it wasn't.
You can get chia seeds at wholefoods - they come pre-bagged and they are pretty inexpensive. They also sell them in bulk but I think those are more expensive. Good luck - acid reflux is the WORST.
