I just started it after reading Lisa's experience, but like you, I want to know how she is doing?
Here's how I'm doing so far:
First day everything went fine with the two pills. I didn't feel anything out of the norm.
Second day, I was very busy and I took the second pill kind of 8 hours after. I had to work very early that day and I was wide awake through the night. I didn't experience any jitters or a fast heart rate. I guess is my own fault for not taking it within the specific time.
I have not started working out, but I am eating healthy.
