i’ve been smoking weed since may 2018 and in the beginning my weight had stayed the same but, my eating habits when i’m sober have become concerning. i end up not feeling hungry all day (when sober) then as i try to eat i end up throwing up... then usually when i smoke weed i obviously eat a lot. since this september i’ve lost a lot of weight i guess, went from 145 to 119/125.. im always cold and im growing more hair on my arms and my back.. is this normal??
