Blimey.....look on the bright side eh? Just want to say that I am coming up 6 months post sleeve and have vomitted just twice post op. I haven't ever had to hold my chest like I'm having a heart attack ever and have only had any pain from eating once (when I didn't chew properly and ate too much when not thinking about what I was doing). I do realise we are all different and have different experiences post op but I would say that the easier you take it and the more you stick to the rules, hopefully the less this sort of thing will happen.
I certainly haven' told everyone about my op but have told all my close friends and family who have been nothing but supportive. A couple of people have asked me if I've had a gastic band and since I've had a sleeve I've been able to honestly answer no! Also, I've gone at it whole heartedly and thrown myself into exercising and being more healthy so people are much less suspicious.
I found the op harder than some but it still wasn't quite as bad as I'd imagined but by sticking to the post op rules I've (touch wood) had a good ride thus far and have also managed to shift over 7.5 stone so far (sleeved on 24th Jan) so I'm delighted. Good luck with your op. x
