Hi
For me personally:
After I get that IV in, which I feel is the worst part, partly because I hate anything needlish and partly because it hurts even with the numbing cream...it ( the K ) sorta feels like a calm... I can feel my body start to relax and the pain drifting away. I do not nor have I ever had any hallicanations, Im just relaxed and then I drift off to sleep
I was told to aways bring a driver with me, it woud be way dangerous to drive afterwards IMO
You will most likely feel sleepy when you get home, I think this is the best sleep I get.
Im not sure if your getting low, med., or high dose but Ive never met anyone who worked the very next day after infusion, that doesnt mean someone hasn't but I don't think I would try...
I wish you much luck with your infusion and I too remember being very scared the first time I had it done.
Hoped this helped in some small way and sorry for any typos,
Dee
