Post op question

Hello all! I have posted in this community a lot lately lol but I just really want to know one thing:

For those of you who are post op and had brain fog + fatigue pre op, how long was it until it went away if it did?

-If the brain fog or fatigue stuck with you, were your doctors able to find the source?

Let me know! I’m having some brain fog that was also present when my gallbladder was still in me, but I had it taken out yesterday. I know it hasn’t been very long so I can’t expect everything to be better immediately, but I’m hoping it gets better in the next few days/ weeks. Give me something to look forward to please!!
