This blog post talks about the side effects of all the anti nausea medication I was on during treatment. It wasn't always just the chemo that made me not well, it was the things that were supposed to make me better too haha.

I am going through the same thing right now after round 2 of chemo. The sleepless nights, constipation even though I am taking coloxyl senna and feeling awful uncomfortable in the stomach and bowels.
