I was on my peg tube for 18 months. It takes longer for some than others. Everyone heals at their own pace and according to their own situation. Pain meds didn't do much good for me anyway, and they always made me nauseated and sick, so I weaned off of them and just learned to take tiny baby steps about eating in spite of the pain. The formula I was prescribed was Jevity. That did not make my stomach upset. However, there are a variety of formulas out there so let your doc know about it and he may be able to prescribe something else. As I was weaning myself from the peg feedings, I would supplement with Ensure Plus Chocolate flavor. It took me over 45 minutes to drink just one can at first. Over a few weeks time my swallowing muscles got stronger and started to function better so it took about 15 minutes to drink one can. Eventually I worked up to only taking about 2 minutes to drink a can. Remember everything has to be re-learned. It takes time and patience. If it doesn't work this time, try it again another time. I still do that. Tonight I had pizza! Although I cannot eat pizza dry the way I used to do, I can eat it by dipping it in marinara sauce. You just have to learn how to adapt and make things work. Good luck!
