yeah, i think its def gear related.
back on 03 i did a few small cycles, ended one in oct 03 and in November 03 I had the same exact thing happen. I felt really dizzy in a crowded place. Usually lunch time in a Subway or something like that. After November, it went away, and never happened again until just recently (after a small cycle which ended in August...). I know it will go away in a few weeks, but just very weird.
to the above poster, I do not think it takes "years" to recover from one cycle... maybe 2-3 months.
