I have -- and I'll see the surgeon again on the 18th and will mention it if it persists (he's the guy who turned me onto Zantac, and also told me that the Oxycodone I was prescribed was most likely not helping things).
Oxycodone is what BBB was prescribed and it was tearing her innards apart. She had severe constipation, so bad that she was eating dozens of prunes, drinking prune juice, taking stool softeners and various kinds and methods of anti-constipation OTC medications without any relief. She finally took herself off the Oxycodone and about 4 days later after expelling the build up of stuff, she was 6 pounds lighter.
While on the Oxycodone, she was having a hard time eating meals too. After just a few bites she'd develop uncontrollable gas and belching. The only thing that soothed it was a square of 85% dark chocolate as soon as it started. The chocolate immediately stopped the belching. She hasn't had the problem since she's been off the Oxycodone for the last 8 days.
Is that sounding similar to what you were experiencing?
