I have been taking Prilosec for the past 3 months. I take one pill in the morning when I know I'll be eating something spicy. I only take it every 3 days and seems to help. All of a sudden my hands swell up quite a bit and I have gained about 7 pounds for no reason. My eating habits are no different, but the weight gain has come on quick. Just wondering is anyone else is having this same problem. I also get little dizzy spells here and there, but nothing alarming.
