I received my sleeve on the 9th. They sent me home with a codeine medication (a pill) and yes you're right it does make you sleepy. but I used that to my advantage. Now I sleep like the dead for about 6 hours and with a CPAP that's not easy. Anyway, My surgeon told me to try not to use the 'codeine medication' unless I really had major pain. (I did have a hernia operation during the sleeving. and that I use Extra Strength Tylenol. The first day it didn't do much and now here we are 5 days out and the Tylenol are helping greatly.
