Day 5 cold turkey

After almost 20 years of heavy every day usage, I’m ready to lift the brain fog. Since medical marijuana was legalized in my state, I’ve been using the luster pod type vape non stop. I’m already skin and bones and I LITERALLY CANNOT eat. I’m nauseous every moment and I’m dripping sweat from anxiety. Haven’t been able to sleep well either. How long will this go on?!? I was a firm believer that weed was “no big deal” but I am truly seeing it for what it is. I’m an addict thru and thru. Fuck I want this to be over with!!!! Any advice on how to cope or how long this will last?!
