I posted a reply about the drinking part of your post but I also wanted really quickly here to post about the motivation thing. Something helped me a ton was realizing that we aren't meant to feel motivated before doing things usually, unless we have already developed a good routine with it and at that point you aren't going to worry much about motivation anyways.

I am sure I am explaining it poorly, but the idea is "Do not wait for inspiration, inspiration is a result not a pre-requisite".

This article explains it far better though: https://www.entrepreneur.com/living/dont-wait-for-motivation-do-this-instead/232349
