I would love to know the answer to this question!!! Is it because the drops aren't as good as the shots? I alternate days where I gain a pound and then lose a half pound. I have been very careful but it doesn't seem to matter. I have been doing this for 18 days and have only lost 7 pounds. I take the drops 6 times a day. I was exercising 5 days a week and I am going to drop that to 3 days a week or so. I am so disappointed.
