What does this even mean???

Posting anon cause I know how ridiculously hateful and judgemental some people here are.

To begin with, I am a medical marijuana patient in a legal state, which is something my doctor is aware of...

But....

I am 28 weeks now, and still smoke every day, between 7-8 bowls a day. My doctor says this is fine, but the problem isn't the smoking: its when I don't that's the problem. I am worried, because if I don't smoke at all, i can't eat or drink. I have zero thirst or appetite, none whatsoever and it is hard to force myself to eat or drink without at least smoking a few puffs to work up an appetite or thirst first. This only concerns me because, I don't have the desire to smoke as much, but end up smoking or having edibles anyway JUST so i can stand to eat. I have gone entire days, like 7 am to midnight without really eating anything, if I don't smoke any weed. I am starting to get concerned, just for the fact that if I wanted to quit (i dont), I couldn't--because then I wouldnt eat and I would feel sick all thr time. What should i do? Should I talk yo my doctor about it?
