and who still suffers from sudden bouts with it two years later, you have my heartfelt sympathy.
If your docs don't have you on multiple meds for nausea, have a talk with them. Zofran (the kind that dissolves under your tongue) and promethazine are life savers. Reglan used to be a go-to drug. But there are risky side effects for those who take it long term. Despite that, it can be a short term option. Also, there are benzodiazepines that work wonders for nausea patients. Just be careful how ya take 'em! Have I used all of these at the same time under doctors' supervision. Yes.
NO, I'm not a doctor. These are things my docs have done for me given my circumstances. Talk with your docs about your own situation. Good luck!
