Question about marijuana

Hi everyone, I’m scheduled for my surgery on 9/23 and I’m really looking forward to it. One thing I’m concerned about is that I’m a pretty big pothead. Obviously smoking is out of the question for a while post op, and I’m completely ok with that. I enjoy edibles, too. My question is, how do you deal with the munchies post op? I was thinking about stocking up on sugar free jello, popsicles, etc. Things that I can eat a high volume of and not ruin my progress. Also, did your tolerance change after surgery? For example, right now I get comfortably high from 10-20mg edibles. Since my stomach will be smaller, will I get equally high from 5mg? Any input from fellow smokers is greatly appreciated. Thanks y’all!❤️
