Re staying at the infusion center, of course it's up to you and him. In our case, my husband stays with me the entire time. I cannot leave the center to get food, and the only things they provide are various beverages and snack items (graham crackers, cookies, etc.). I would be awfully hungry without his help. We bring books and crossword puzzles and plan to stay the day. (As I said earlier, we're usually there 6-7 hours, by the time you account for blood workup, premeds, chemo meds and pump installation.) He goes in and out as needed to visit the hospital cafeteria or Panera (in hospital) for food and snacks. Plus, it's nice to have someone there to talk to and just be with. Edited to add: Each infusion station at our hospital is also equipped with a TV, and there are books and magazines to read. Maybe most importantly, chemo is a good time to sleep! The quiet and the drugs are conducive to sudden and lengthy naps.

Re fluids, chemo can be very dehydrating--even more so if you're dealing with vomiting and/or diarrhea. I have standing orders to get 1,000ml of fluid on pump removal day and the next day, when I get my growth factor shot (Udenyca). I have declined in recent cycles because I didn't need it, but I have used this in the past, and it can really help.

It might give you some peace of mind to go along. Also, the infusion center will get to know you
