Nausea tips?

I'm trying them all. Mints, ginger, ginger ale, snacking, sea bands, etc. I cant stop throwing up at least 2 times a day.

I'm not constantly nauseous (or maybe dont notice it as bad because I've been on low dose chemo before so nausea is just old hat to me), but when I am nauseous its terrible sudden, and I vomit most everything I try to eat until about 630 PM when it dissipates for about 2 hours.

Do I just have to eat nothing from the time of waking up-630pm? Because even when I do that I still throw up. It just feels like less of a waste of money.
