I have too many years of muscle memory from drawing comic panels; I always draft from left to right...even though, when I read comics, I accidentally read from right to left roughly 50% of the time. XP
It's weird because I read more western comics in general, but it may be because I tend to read more eastern comics in one sitting (one page of a comic strip vs. a full chapter of a manga) so my brain learns to habituate to the latter.
