On a 319/320, I would avoid 1B like the plague on any redeye. I recently "scored" a free upgrade, only to be put in this seat. The FA had to keep the galley light on for a good portion of the flight for service reasons, and it shined on me and kept me awake. I also got bumped regularly by lav users. If you get this seat, at least bring eye cover -- and maybe some shoulder pads as well.
