I use Esomeprazole Magnesium which is the generic for Nexium. I take 4 20 MG a day which is way over the recommended dosage but is needed because without it I would have tremendous reflux at night. Since that dosage is very high and effects calcium uptake, I take D3 which supposedly aides in the uptake. I'm not a candidate for the wrap or LINX since my hiatal hernia & Barrett's is where the wrap would be and would cover up the area which would over time go cancerous. So I'm pretty much stuck with the high dosages of meds.
