I have been told 4-6 weeks, but just via email. I know what you mean, as I really want my surgery towards the beginning of the summer holidays because of childcare. I went for a consultation at Healthier Weight last week and they could do it the following week, so it's tempting. Although in the long run waiting another month and having the right surgeon and aftercare I reckon is the more sensible option....
Keep me posted on what you decide x
