I used to think this about myself too but when I looked at it in TFM terms of the benefits of benefits I realised that I don't want abstinence per se but rather the benefits that abstinence brings, such as peace and freedom from worry.
As you said, ambivalence means wanting two completely opposite things. There is no part of me that does not want these benefits and so there is no ambivalence left to deal with.
