I have been on Prevacid, 30 mg, twice daily, for about a month. It finally seemed to kick in after 4 weeks and I had 5 glorious days of no acid, or very little. I then reduced my dosage to one 30mg capsule daily. Within two days the GERD came back full force! Is it better to go back to two pills? Is it common that it would come back so strong? I'd rather take the two capsules again than have this! Ugh!
