I mainly talked with the nurses and other patients who were hooked up to their IVs. It was pretty entertaining at first meeting new people. Other than that if you don't want to talk then you don't have to. The nurses periodically ask how you're doing and leave you to yourself. You can read, sleep, watch movies, go online, basically do whatever you want, you just can't leave. If you need to use the bathroom then you can take the IV with you but they prefer it if you go before you're all hooked up. I highly recommend that you do. I had to pee so bad after my first infusion.
During the infusion I started feeling sleepy. That was from the Remicade as it can make some people tired. I was given a non drowsy antihistamine before each infusion, they also gave me Tylenol too. Don't take Tylenol or an antihistamine before your infusion (unless they say you can). If you start to feel weird in any way be sure to let the nurses know yet they are usually in the room monitoring the patients. You're blood pressure is also monitored.
Most people are able to drive afterwards but if you want you can arrange for a ride to see how you feel after your first one. I think I probably could have taken care of myself after my first one but I had a ride just to be sure.
Good luck and let us know how it goes.
Edit: We were not provided snacks but were allowed to bring our own. We were provided blankets though and the infusions were done in our doctor's office which wasn't too far away from the hospital.
