I managed to get my non-showdown winnings from badly negative to near breakeven by:

Picking better board textures to c-bet / double barrel
Picking better villains to c-bet / double barrel
Being more selective about c-betting/bluffing in general
Floating c-bet bots in position more & punishing their predictability.
Tightening up a little preflop.

The last one worked for me because I was pretty loose preflop and ended up in marginal spots vs loose shortstacks where I c-bet a lot with trash or 2nd pair no kicker and had to give up a lot of raised/cbet pots.
