spider,
do you have any other symptoms of b12 deficiency? I have been on protonix over a year, and have been on double dose 2x a day for about 2 months. My tongue seems fine for now, but my muscles ache and I just have been feeling so weak. I also have probs swallowing from time to time, so I dont eat really well...So, Im wondering if this could be my problem too. I recently started taking b12 supplement, and folic acid, along with a regular one a day vitamin.
