Interestingly I have had an email from the surgeon today who has confirmed that, this far out from my operation in March, there would be no issues with diving! :)
Hope this is of use to anyone who is considering it post-wrap!
Thanks Denise, I'm actually heading off around the world in October. Eating still needs to be done carefully, and I get occasional regurgitation of mainly saliva, but it is getting a lot easier. I hope that with a chilled out trip, I can control what and how I eat a lot easier. I find that if I eat something small before a "main" meal - e.g. a few Pringles or a bit of bread before spaghetti bolognese, it tends to "warm up" the oesophagus and make things much easier.
