Everyone is different, and I can only speak to my experience, but here's what worked for me:

I meditated on the differences I felt when high and not. Getting beyond the physical sensations, which are very nice, the biggest difference was that I was able to relax my mind and enjoy things when high. When I was high, I was not eating an apple and worrying about my daily/weekly/big-picture stresses. I was just eating an apple. I already knew that this was preferable on an intellectual level, but getting high allowed me to feel it - to know that it was actually like.

The first time I quit, I had not practiced enough to enact this in my non-high state. Even though I knew I wanted it, I let my thoughts hurt me. This last time, I had practiced/meditated enough to naturally be in the state of just enjoying an apple (btw - I don't just eat apples all day). Enjoying nature, taking walks, and my interests/passions also help a lot.

I don't know if that will be helpful to you, but I hope it is :^)

Thank you.

My advice, unasked for, is threefold. First, accept that st first it’s going to be a little messy. Your sleep might get wonky, you might feel a bit depressed or “blank” and you might even have hot flashes. It will pass, and little tokes here and there don’t so much help as reset the clock. Second, your appetite might take a hit, but it’s important to eat well. Finally, keep yourself occupied with something low-effort that you enjoy, preferably something that makes you smile. If you find yourself ruminating don’t dive deep into it, just quietly say “no” and move on. When you slide back into rumination, same thing, no big production, just “no” and think about something else.

Accept that this will take time, and you won’t feel really normal for a while, but you will feel OK again.

Thank you.
