I’m typically the “tough guy” with these things, but I can tell you I would have been a definite no go in that scenario. I had bypass early evening June 4. I met with my surgeon early morning June 5. I felt great & couldn't wait to go home. I left the hospital early evening June 5 still feeling good. Then, the nerve block and medications start to wear off.
A couple days out, I was fighting horrible gas pain that is only resolved with time, walking, and drugs that make driving unsafe. In my opinion, merely being in the room would be a challenge. I could not imagine being my best self for an important sales meeting. I would suggest presenting 100% of yourself in a couple weeks instead of 25% of yourself Friday.
Good luck!
