Yamaha DTXpress/DTXplorer/DTXtreme

I went away for 3 weeks vacation, after a week or so I started to get 
short fused over the dumbest things. I just got back home tonight and 
realized what it was, I picked up my sticks and enjoyed a few hours 
of thearapy. I should have looked for a studio when I was on 
vacation, only if it were for an hour. I've only had my DTXII since 
December, pretty crazy huh. You know what else? I was nervous about 
losing a little from being away,  but oh no....... my limbs seemed to 
belong to someone else, I was hitting beats that I had a little 
problem with before I left. Anyone have this sort of thing happen?
