Hello. I used this brand because they have no alcohol. At first I was worried since there was no taste to them. For me it took about 4 days not to be hungry which was difficult. I was a serious sugar addict though so that had something to do with it I am sure. I did a 40 day round and lost 28lbs. And I cheated in small doses in the end and stalled myself a little. 1 bottle lasted about 30 days then I bought another to finish out the remaining days. I am doing another round in about 2 weeks. For me I stabilized perfectly in P3/P4. I never went 2lbs under/over. The directions say 10drops 3 time a day but I switched that to 6 drops 6 times a day and that made it easier on me. I am extremely happy with them. Good luck.
