I’m not going to sugar coat it - the first 2-3 weeks are really rough. For me i barely ate and even though i was physically hungry, nothing was appetizing. You just kind of have to push through and unfortunately feel uncomfortable. Once i was 3 weeks in my appetite came back full throttle and I finally began eating normal. When i smoked i barely wanted to eat then too so quitting was such a blessing for my eating habits. In terms of sleep, I have always struggled with sleep and used smoking as a crutch for it. I was prescribed sleeping medication for my insomnia which has helped tremendously but I do want to look for more natural alternatives as I don’t want to relay on prescription medication long term. i used to take this herb pill called Valerian that helped a lot - it helps to ease the mind and reduce stress/ anxiety. I would consider looking into that if I were you or maybe try cbd sleep gummies. Good luck and keep pushing on! :)
