Even 20 years ago they were still working out the fine tuning of the RNY.
I dump on sugars and fats. I wanted dumping and 20 years ago it was about 50/50 that it would happen. So, not only do have have general restriction but I am also forced to limit sugars and fats. Even though dumping is considered a "complication" I count it as a win.
Yeah, meds can be an issue. Most time-released meds are problematic though some seem OK. I imagine it makes a difference what time-release mechanism is and where in the digestive process the meds are absorbed. Additionally, at least for me, are for meds where I can feel an effect the effective period is not as long as expected. Something with an 8 hour period of effect lasts 4 hours, sometimes 6 hours, never 8.
As I've stated here previously, I manage to eat a complete meal about 50% of the time. When my stomach says to stop I've learned it's just best to stop. When I am not feeling well or I'm fatigued my digestive system just shuts down. I've always been this way since I was a kid, but surgery just made the situation one that spirals out of control quicker. This makes meds likewise worse.
I've learned to cope with these issues, just chalking them up to part of the joy of being me. I'll takes these worries over being 500+ pounds overweight in a heartbeat. Were it not for surgery I likely would be completely disabled or long dead. I still never regretted having surgery for an instant.
Good luck,
