when were you able to painlessly sleep on your side of stomach after surgery?

my surgery is in a few months and i’m kind of scared because no matter what, i cannot sleep without somehow ending up on my stomach and i know that doesn’t sound the best for recovery at all.

i heard a lot of people sleep on the sofa recliner for the first week, but how long did it take for you to be able to sleep on your side or stomach after surgery?
