Last year I was diagnosed with acid reflux and was perscribed by my doctor to take Prilosec OTC (I didn't have insurance). At the same time, i went from a local gig to OTR driving. I wound up gaining 25lbs but I figured it was from the lack of movement and bad diet.
Well, just 2 months ago I quit taking the Omeprozol as my stomach had started giving me other problems. My current doctor told me to stop taking the meds. I quit taking the prilosec and in 2 months I lost 28lbs and my man-boobs (which is a side-effect too!) I got a ton of energy back as well. I know this was what caused it as I didn't change ANYTHING else, just stopped taking the pill once a day (I now use Pepcid complete when needed)
Once i told my father this, he too quit taking it Omeprozol (he had prescription form) and he lost 17lbs in 3 weeks!
Just a thought, you guys might want to try to switch to say Zantac as it has none of the above listed side-effects.
