I know many of you have been suffering with heartburn. I have it on and off every day. I usually take Tums and they work fine, but sometimes I'm worried that I might be taking too many (if I remember right, 6 is the limit, correct?) Or I can't remember how many I've already had that day as it gets worse closer to bedtime. Would it be better to just take Pepcid? For those who take it, do you wait until your heartburn hits to take it or just take it every day regardless? The one thing I like about Tums is how quickly they work. Does Pepcid work quickly too?
