I didn’t really have any problems I took that nausea medicine religiously. I avoided spicy foods and citrus.. I ate a lot of protein. I ate small meals. I would say the most important thing is to be hydrated. On the days that I had treatment, I didn’t really eat anything prior to. I ate after I had no idea how I was going to react to all of it. That’s how I started. I never changed it. One of my favorite things to eat after treatment was Chick-fil-A’s macaroni and cheese it was very soothing for my stomach.. during treatment I noticed there were quite a few people that would eat throughout their treatment - peanut butter sandwiches were a favorite with several of them.
I will share with you that most of the things that I ate during my treatment I can’t stomach now. Prior to chemo I really loved spicy food. I can’t tolerate spicy food anymore. I’ve always been very healthy ate healthy. Ive actually did a lot of research to bake sugar-free and I have totally adopted that into my new normal.

AmaleneCreggy,
Hi and welcome to the site. Everyone on here is so nice, helpful and supportive. I too have/had DLBCL stage IV and had treatments of RCHOP chemo. I've been in remission for 4 years. When I had treatments I made sure I stayed hydrated. Even during the chemo I would drink lots of water. When I was nauseated I ate a bagel with peanut butter for the protein. Also I had milkshakes with fruit, ice cream and kale. I also made sure that I took my antinausea medication on time and never skipped. I hope your treatments go well. If there is anything I can answer for you please let me know. Kelly

I never had vomiting but some nausea. I started hating all foods for about 4 months so if it sounded good, I are it. Fruits, veggies, especially chicken soups. I kept losing weight but tried very hard to eat protein based foods. And I ate smaller amounts but more frequently. I had NHL, DLBCL also located in my spleen only so healed from my splenectomy a month before R-CHOP ending August 1, 2024. I've just started to get my appetite back. But still hating a lot of former foods.

Get an exercise program started and eat protein and lots of water

Protein is important. As long as you don't have any medical reason to limit it. Lots of water. Exercise if you can.
