Thought I'd just post a quick update: I had my op on 12 May, just over 8 weeks ago.
The two weeks pre op and about 3 week after were hideous. The pre-op diet made me feel terrible (but I did lose a stone and a half) and post op I jus felt awful.
I was horribly constipated, was re-admitted to hospital at one point for enemas and 'manual evacuation' which was incredibly painful.
I really did wonder if I'd done the right thing.
However, now, 8 weeks post op, I'm eating normal food, albeit very small amounts, drinking plenty of fluids and I feel pretty good :)
I've lost nearly 4 and a half stone in all and have shrunk a lot! I am wearing clothes if grown out of years ago and have had to get rid of loads of things that just don't fit any more.
I still have a long way to go, as of this morning I weigh 20 stone 9lb. Which is frankly disgusting but is better than the 25 stone plus I weighed 10 weeks ago.
I don't know is anyone is contemplating having weight loss surgery, I'd be happy to answer any questions about it to the best of my ability. :)
