Interesting and good question, Belle ! I've had 4 caesareans, but the last one was 14 years ago, so I can't remember anything about pain relief post surgery. It is different, though - a lot more invasive, a substantial cut, and considered major abdominal surgery, whereas the sleeve is not 'major' (yay!) I'll be interested to hear others' experiences and advice, too.
How will the sleeve likely impact on your thyroxine medication level ??
