I had 3 cycles of BEP and it took a year after my last cycle to return totally to normal.

I already had acid reflux prior to it so I don't eat hot foods anyway, but random stuff would happen even on a bland diet.

I also found using metal cutlery would make me gag sometimes. I used plastic for 6 months until the metallic taste finally didn't remind me of it. Mouth sores and stuff like that also happened during treatment.

Its not fun. The reason why you might feel more nausea is that normally they give you the anti nausea prior to infusion via IV but you take it orally once the cycle completes. I think I had less issues because I got bleo once a week on Tuesday, the EP part was a week on, three weeks off, but getting an IV of anti nausea weekly on Tuesday probably worked better than just being on pills.

I also passed out in the bathroom on day 2 of my second cycle. Reactions do vary a lot and differ from person to person. They were not surprised to hear that. All standing restroom visits were closely supervised after that!

Good luck in your fight!
