Sometimes I do, sometimes I don't. Depends what I feel at the time. After a long time waiting, I can see how the need to feel normal is massive, and that's why I didn't abstain on my most recent TWW (and got a BFP!)

A really good decoy is to drink water out of empty beer bottles. (west coast cooler bottles are good too!) I found this works particularly well if there's any peer pressure or if you want to keep it a secret.

Good luck!
