One of my friends became a CD counsellor and I had thought about it for a long, long time (around a year). I plucked up the courage to ask her and she has been amazing. No, it isn't through my GP. If bmi is over 40, the GP has to sign to say they are aware and that the information you've given is correct (they aren't signing to give permission).
I felt I was utterly at the end of the line diet wise. I knew I couldn't face 2 years of a pound off here, a pound off there through SW etc I had tried and failed so many times. The reality of being a shade under 24 stone was just too high a mountain to climb at such a slow pace. I had even done research into gastric bands etc even though it wasn't a route I wanted to go down as the thought of surgery scared me. My options had become incredibly limited and my relationship with food was just appalling. Taking food out of the equation is giving my brain the chance to totally re-train, break old habits, analyse emotions and re-build new ways of living without food being a constant crutch.
Cost varies, I pay a shade under £40 a week. I am on soul source so the shakes, soups, bars are literally everything. I used to think that is very expensive as I don't spend that much in the supermarket. The truth was though that I conveniently 'forgot' about takeaways, stuff from the works cafe in the morning and trips to the shop across the road for lunch. I do a big shop at the beginning of the month (around £75) on OH's CC and that lasts for the month for food for him and basic veg. and toiletries. I then pay for my CD myself and I'm happy with the cost as I finally feel I like myself to invest that much for around 11 or 12 months to get to goal.
I dread to think the amount I've wasted over the years signing up for WW/SW etc online for 3 or 6 months and then fallen off the wagon within days.
I even bought a batch of Alli when it came out and never took one, utter waste of over £40
