When was stomach not as sore?
I can't answer about the tummy soreness, I had relatively little and no problems sleeping in bed or getting in and out of chairs.
But I can talk about the tireness - I'm sore the pain meds come into play - but it also takes some time for the anesthesia to leave your system. I'm still a little tired 2 weeks out, although I did not feel the need for naps in less than a weeks.
Hope your soreness leaves soon!
