I was taking Prilosec 40 mg for 12 wks, then my GI doc told me to take 20 mg and stay on that. Well, I've been taking the 20 mg now, for a month or so, and now are having more problems with increased acid reflux . So yesterday I took 40 mg, and had the worst acid reflux in my throat all during the night, it burned very bad all the way in my throat and felt like my mouth as well. The PPI I am on is Prilosec, and the others for me are very expensive. Should I discuss this with my doc again, and what could the problem be with more acid reflux, I can't play around with this, since I have Barretts, any advise would be appreciated.
