Appetite help? - sickness

Hey guys, I’m 20, been smoking daily since 15 and it’s gotten really over the top with starting and ending my days high. Every time I try to quit I struggle so much with my appetite, let alone sleep - I haven’t even been able to get to the sleeping part so much.

I’m currently in the process of weening myself off it by smoking less and less daily, though I’m still struggling with just feeling sick and when I see food it makes me want to gag.

I’ve tried the teas and small portions etc. any one got any tips / just looking for people with similar experience to share their story? Thanks heaps
