That is the main thing LDN has done for me. I used to take 1 to 2 Provigil a day and still even take a nap!! Now, I might take 1/2 of one if I know I have things to accomplish that day just to make sure. But I usually have energy to spare and don't need it. It's (LDN) truly been a Godsend to me. And, just to be clear, it's not the hyped up type of energy you get from too much coffee or some sort of stimulant. It's just a good feeling of positive energy and the actual desire to want to get out there and do something! I hope you have a positive experience with it.
