anxiety
"This is my first day on Gapapentin for anxiety, and I have experienced truly amazing results!  I am free of anxiety and work, and excessive thinking has greatly diminished.  I am thinking clearly, and there are no apparent side affects.  I began to feel the calming effect with 20 minutes of so.  I hope that I will continue to receive this therapeutic effect on such a low dose, and do not build up a tolerance."
