I went ahead and ignored my own advice and started with 2 caps.....
I took my 2 caps at around 10:00 AM. It is almost 11:00 PM now and I am just starting to feel my energy slow down. I have been pretty wired all day. At first, I didn't think I felt anything. However, after about an hour I was ready to go. What I was more impressed with was the appetite control. I didn't feel like eating at all throughout the day. The problem with this is.... during the day I started to get a little shaky from the strong stim and lack of food. This passed once I made myself eat a bit more food.
I think Slim FX is a great product that does EXACTLY what the bottle says it will do.
My only caution is to make sure you force yourself to eat a little more(you really won't feel hungry) so that you avoid the stim shakes and tremors.
