This is my second time on Phentermine. The first time I was on it, I drank like 3 21oz coffees per day. I still lost weight really quickly.

I'm not having as much luck this time around though & I'm only drinking 1 21oz coffee per day. But I know it has nothing to do with the coffee. I was on a much stricter diet the first time.

Well, they say Mt. Dew has the most caffiene of any softdrink. And all the times I've been on Phentermine, I've drank enough of that to put someone at Mt. Dew's kid thru college. I drink coffee as well and it hasnt affected my weight loss any. Something to keep in mind with phentermine, I've seen it vary so much from person to person there really is no way of knowing how it will affect you until you experiment with things like caffine, when you eat, what you eat, etc to see how to get the most out of it.

Hope that helped!
