Luckily I didn't have any pain but I also didn't have any hernia repair or gallbladder removal; so that probably minimized the amount of discomfort. One thing I highly recommend is using a recliner for sleeping - I definitely could not sleep comfortably when laying down for about 5 days post op. A recliner was so much more comfy. When I came out of surgery I had absolutely no pain - I slept almost the whole day away! I took my pain meds, but it wasn't truly necessary.
Best wishes for a really successful surgery!
