Anyone undergo MVD surgery for TN? Tips for recovery?

I have been fighting TN for 2 years (finally got official DX this past February). Tried all the medications they could shove down my throat which only left me with new medications that I am now allergic to. MRI doesn't show a clear blood vessel compressing TN nerve but he does see a tiny one that could be causing the issue which is why he will do the rhizotomy if there is no blood vessel. Im nervous as hell but going into this with full understanding that this may or may not help. My question right now is I'm trying to get an understanding of how recovery will be so I can do the Mom thing and let my husband kids know exactly how. They are supposed to take care of mom LOL! How did you sleep? Did the pain medication help at all and how long did you have to be on it? Did they shave the whole side of your head? What was the worst thing about recovering? Would you do it again if you had to? Thanks to anyone who takes the time respond! Surgery is Sept 15th so the nerves are taking over!!
