I am not a real expert yet... I can only tell you what my side-effects are:
1. A great thirst to read as many different books on as many different subjects as I can think about 
2. An incredible (sp) feeling of confidence when I have to take an exam.
3.A bad habit of not spending as much time with my reading assignmemts as my fellow classmates have to
4. Learning how to relax...deep total relaxation
