Hi and welcome to the Chiari forum,
We all will have a different experience so it is hard to say what u can expect but many of us do have a journal with our Chiari experience in our profile page.....
We also have a list of items for the hospital stay...this can be found in the Health Pages.....and we also have a thread for surgery dates, if u post ur date there we will post a Prayer Thread for u.....

I had surgery 4.5 yrs ago, I woke in recovery, and moved to ICU where I was for 2.5 days I did not get out of bed until the last day as I was hooked to monitors and oxygen....I had a reaction to morphine so could be part of my issue, plus I also had tissue harvested from my scalp for my dura patch so I also had a drain in, so I had a cath, and my legs had these moving leg warmers to keep circulation going....as I said we are all different and it will depend on how ur body responds.....
Once the meds were changed I did well....and am so glad I was able to have the surgery.
