I've had 5 hospitalizations. For me they have oddly kind of clustered. I avoided it for many years (mainly because my pdoc did not want another doctor messing with my delicate and not traditional meds; now she's at the same hospital that I go to so she maintains input). But I had one IP stay for a med change in 2009. Then I was in twice in a few months in 2011 and not back until I had 2 stays a few months apart in 2015-2016. And then I've stayed out again for 14 months. Every time I've gone in I've felt like it meant I was taking a huge step backwards but in the end I really got a lot better within a few months of the admission, even when it took a 2nd admission to fully adjust meds.

I hope it is the same for you.
