My bottles came 2 days early. I’ve been consistently taking them for 4 days and have lost 2.5 pounds. I haven’t been eating as well as I should (I start off good, but gummie bears are a curse). I read some people said the pills made them feel hot, but I haven’t noticed that. I drink 2 cups of coffee in the mornings and haven’t noticed any kind of interaction between the pill and the coffee.
