I've been taking these for a couple of months for acid reflux and IBS symptoms- I also take digestive enzymes, and basically by taking this with the enzymes before each meal I was able to stop taking Nexium and have had the same results. I'm still not cured though, so I'm trying different things, but it's worth it to not have to take a proton pump inhibitor (Nexium, Prilosec, Prevacid, etc.) indefinitely. The taste, being sugarless, is pretty bad, to be honest, but you get used to it. FYI: My symptoms are basically pressure in the stomach, and a congestion/gurgly feeling in the throat after meals. I've had all the GI workups and they couldn't find anything, so they say I have IBS.

This made me feel terrible- not sleepy at all- it made me jittery and nervous for a few hours while I tossed and turned - perhaps the dose is too large but I'm not going to find out. I'm 32 and I read later that melatonin is not recommended for people under 40, which also might have something to do with it. Now I'm exercising more and sleeping better without any supplements.
