How to stay consistent with treatment?

So...my wife had a pretty epic blow up at me this morning because of my inability to see the problems I am causing.  I get into this crazy cycle where I am doing okay with seeing a therapist and taking medication, but then inevitably I "fall off the wagon". i.e. start missing therapy appointments, stop taking medication and then the cycle starts all over again.  My question for the successful people is, how do I avoid this?  I am not even aware that I am doing it.  That's the main problem in my marriage is my lack of awareness.

This article basically describes me to the letter:

I am convinced it matters, btw.  I just often lose sight of why it matters or again, my awareness.  Thanks in advance for the tips and responses.
