Nausea Advice?

Mom had her 2nd chemo last Wednesday (alimta/avastin/carbo) and last night had a bad bout of nausea that resulted in a little incident with some cold coffee that didn't want to stay down with a Docusate Sodium pill (stool softner). I was such an idiot to ask her to take the pill, but she'd only had minor nausea after her first chemo treatment and I didn't think. *sigh*

So anyway... today in addition to having zero apetite, she is afraid to swallow anything in case it comes back up. Her apetite disappeared yesterday and she only had about 500-600 calories all day. I track everything she eats and she's been averaging somewhere around 1300-1500 calories each day since coming home from the hospital at the beginning of October. I've been hassling her a bit each day to eat more because she is losing weight on that regimen, but I can't bear to hassle her now after last night.

She's been sleeping a LOT - pretty much all day yesterday and judging by her demeanor today, she'll do the same today. (She's sleeping in her recliner beside me at the moment.) She woke up, was awake for an hour or so, then conked out. She did that a few times yesterday too, so I imagine she'll be following that pattern today. (Today is day 5 from the chemo infusion.)

Where I need advice: should I try to get her to eat more today? Those of you who've been through this - are there days you didn't eat much of anything? Was that okay? What helped you when you were battling nausea/fatigue? Anything you can pass along to help me help her?

Many thanks for any advice you can give me. I feel like such a meanie for hassling her about everything. I need to know which battles are the most important ones to fight and which to let slide for another day.
