Thanks for this thread! I am in nursing school and I was completely fried by the massive amounts of information thrown at me. I am working on getting tested, but in the meantime I take caffeine, ginkgo, ginseng and omega-3 fish oil. It helps, but not all the way. And I have to be careful with the caffeine -- if I take more than 2 in a day, I can't concentrate AND I'm jittery. A lot of what I've read here is what I feel every day, and BTW the digital recorder does help with lectures if you're able to do it. Thanks again.
