I have gerd. and my doctor recently raised my dosage from 40mg to 80mg daily of omeprizol. do i take it forever? i've been on omeprizol for 2 years no

Consider 2nd opinion: If you only have GERD, then a) 80 mg daily is too much and b) is not recommended to be taken for longer than a year. An EGD/ endoscopy would be important (and repeat one if it's been a few years). I'd suggest getting a 2nd opinion from a GI specialist. Also really focus on lifestyle changes- no smoking, reduce alcohol/ spicy and acidic foods, elevate the head of the bed.
