hi honey, i went with wga 3 weeks ago, on the morning you just have blood test and give a urine sample, then they come give you a small injection that stops blood clots after the op, the hospital and staff are first class, but the aftercare with wga is very poor, three weeks on i am still chasing them for my appointment to go back for the post op xray they keep making excuse after excuse. finally spoke to someone this week who admitted they are so overbooked at the moment with banding that they are struggling to keep up with the post op xrays and dischage appointment ( they are now doing that over the phone to catch up !!) but i must say the operation was great and they couldnt do enough for you when you were there. and also as mentioned find out where you are on the list. i was also 7th out of 8 ( i personally think they do the THG patients first and the WGA patients last. i went down at 5pm. its a long while to go nil by mouth if you are last on the list. Good luck , hope it goes well for you.
