I noticed you haven't been welcomed yet...
So a big hello from me and welcome to this really great forum.
Surgery will come around quick and starting opti...well... we all godda do it unfortunately, but for a very good reason. If you're like me you might actually find you like some of the stuff. I enjoyed strawberry shake and the bars, weird, I know, I don't like anything else strawberry flavoured.
You will enjoy the rest of your life, it will make so much difference to you.
Plenty of really helpful advice here so spend some time searching (or lurking) around.
Best of luck for your surgery.
