Kudos to you that you keep trying! The only hopefully helpful things I can tell you are:

1. We as humans can get used to anything- we have a remarkable capacity to adjust- I used to absolutely hate drinking water, but over time I now really enjoy it & even crave it sometimes
2. Generally we adjust better to smaller changes over time instead of bigger ones all at once- I have used this concept to eat healthier, more veges and much less if any sugar, which I was hooked on for most of my life. Now when I eat something sweet, I don't even like it.

Sorry the milk you like is so expensive- that sucks!
