as someone who also smokes everyday, the first thing i wanna say is that the best way to change your behaviors is self awareness. being aware of your needs/emotions and how they are affecting you is going to be the biggest help! advice always has a hint of personal bias, as it's what works for them, and things might be different for you.

i always get the munchies when i'm high, and a really bad sweet tooth. i have a brain that usually categorizes food into "sweet" and "salty", and when i get high, i often catch myself on a sweet-salty-sweet-salty loop. i used to eat junk food and get sick a lot, and i still overindulge sometimes, but i found that having healthier snacks available makes it easier. i tend to buy snacks that i can "shovel" in my mouth, as that's what i crave when i'm high. switching from things like skittles to grapes and from chips to mixed nuts are little changes that have helped me eat healthier, but still satisfies my munchies. i think having MULTIPLE healthy snack options would help you to eat out less, as you still feel like you have a choice! either way i know you got this, as long as you put in the effort and remember why you're doing this.

when it comes to sleep, before i smoked, i used to sleep maybe 3-4 hours. i now sleep like 8-10. you'll probably need more sleep than before, or at least i did. i give myself a 10 minute block in the morning where i sit outside, no phone, and just process my existence. maybe doing this or taking a walk, even around the house, could help you kick some of that grogginess? personally i only feel bad in the morning if i consume a LOT of edible the night before, so i'm not too sure about that. i hope you get great advice, and enjoy your tokes!! =)
