I did, tried it from holland and barratt, and no effect, spoke to the lady at my local health shop and she said she had no effect either. I`ve started using chromium picolinate, high strength which is good for blood sugar levels, curbs cravings, has helped and its cheap at �5 a bottle for 2 months! also just started a detox thing from boots to kick start my diet. and been to gym 4 times this week helps! good luck and dont starve yourself, do it slowly and you will keep the weight off.
