Started greening out

Hi new to the sub

I have been a heavy smoking for about 5-6 years now and just recently have started feeling weird when smoking. I’m basically on the verge of greening out but i manage to talk myself out of it. I’ve never fully greened out before with the puking and all but i get random waves of dizziness and i get cold and sweaty + my heart starts racing for a few minutes at a time.

For the last few months i’ve definitely been smoking more without taking T-breaks like i used to but i’ve been fine till just days ago and idk what to do. Im totally going to take a break for a bit but i’d like to go back to it eventually.

Thoughts or suggestions?! Has anyone ever felt like this and continued smoking?
