continuation bets losing money, how do I adjust?

[Dommer]

Out of curiousity I recently started recording what I was winning/losing with continuation bets. I include times where I have KK/QQ/JJ and an overcard hits because I don't really want a call there and will have to give up to any aggression. Well in just this past day of playing I've lost 100$ just on continuation bets, which is what I thought. I'm losing money by continuation betting.

So.... I am profitable with AK/AQ/AJ and all pair type hands, so obviously continuation betting isn't making me unprofitable here, and its possible I am just running bad. But it definitely does seem like a leak, how do I adjust my play accordingly? Raising AK/AQ/AJ seems really pointless if you aren't going to make a continuation bet, it seems like you are going to get the pot taken away from you very often. Limping them sucks as well. Well I have no idea what I need to do, any ideas?

PS. I only try continuation bets against 1-2 opponents and I usually bet near pot size (7 into 8, 8 into 10, etc)
