Thanks! I think there's a book called "why we sleep". I'm reading that next.Having a good sleeping routine is crutial for me, and it has huge effects. I encourage you to read a bit about sleep hygiene.
Good luck on your busy week, I hope you can manage it.
Is cool you are exercising, in my experience it also helps!!
good luck with the urges, they are a bitch, but think that they are there just to train you to overcome your addiction.
Cheers, wish you the best
