I take 150mg of zantac in the morning and evening and it has been working so far. Although, last night i woke up to fire breath as well so it's effectiveness is probably wearing off lol
Just plain ol calcium carbonate like Tums, has been working wonders on my heartburn and is completely safe throughout pregnancy.
I've been taking mepredec for a few years now, and apart from the odd bit of heartburn in the evening that runs would sort out ice has no issues. Maybe as the doc for that. Take one in the morning and your good to go x
