Good morning All. Gee wizz I hate it when they change my meds. I have been taking prevacid for years & it worked just fine. Then it went over the counter, more expensive but and I had to take 2 smaller capsules instead of one larger one but still fine. Then I couldn't find it for a while & had to scramble. A Sam's pharmacist gave me a bunch of samples that were about to expire and when they ran out I tried prilosec which was almost as good but not quite. Now they come out with a 24 Hr version. Still smaller caps but supposed to last 24 hrs. IT IS NOT WORKING. Now I don't know if it is still too low a dose even though it lasts 24 hrs and am not sure if I can take 2 or not, plus 2 a day now will again be more expensive! Grrrrrrrrrrrrrrrrrrr!!!!!!
