I'm the opposite - when the doc told me I needed IVSM ASAP I went to the infusion place and they had me do the first one there and I did the next 2 at home. Now that I know you can do it in the hospital too, I'm glad I did it this way. There's a shunt in your arm with a covering over it so it's easy to access it when you need to. I didn't know I was supposed to drink a lot of water beforehand so they had trouble accessing the vein on the outside of my forearm so they did it on the inside. Drink lots of water! I only had to do it for 3 days total (1 hr each) so it wasn't a big deal. There is a weird taste so make sure you have some mints or gum handy. I had more trouble with the days afterward dealing with the side effects than the infusion itself. Ambien CR became my friend Lots of people tell me, "oh, I could never have done that!" and I say YES you can!
