This has been happening for me every night for the past few nights... I feel really great!...right when I'm supposed to be going to bed. During the day, when I have to interact with my coworkers, I am anxious and depressed and completely wooden. Does anyone have experience with this? I have to wonder if it isn't the brand I'm taking. But I don't think it's typical for a generic to retain it's payload for hours and then release it nearly 16 hours later....typically the problem has been that too much payload is released right away. I'm also taking 60 mg of BuSpar. I'm going to experiment with taking less during the day...
