20 years heavy user day 4 done

Help. Ive felt exhausted all week since I quit weed after 20 years of smoking all day everyday and dabs. Feel nauseous in the mornings when I workout or swim as I usually do. Get tired so much faster too. Extremely tired all day, metabolism is fucked up (hard to feel hungry and not shitting like i normally do) This is hard AF but i decided to get clean for my first born baby girl who will be born in april
