I had revision to sleeve on the 30th as well! One night in the hospital and they took my drain out before I left. My surgeon said that is his preference and I was ok with that. As for the removal it didn't hurt necessarily but did surprise me. Felt it come out and it was longer than I realized. After a sharp intake of breath, due to the foreign feeling, I was fine. Hope your removal goes well!
