Suggest Treatment For Vomiting After Coming Off From Cannabis

Hello, I recently slowed way down on drinkng beer and smoking tobacco,and i wont lie i had smoked k2 for somtime as well. I quit the k2 and beer completely cold turkey. Ever since then for a week and a half i have been experiencing weakness, tiredness, vomitting, sweating, cold flashes, sick/hungry stomach, have tried vitamins and water and powerade. everything I ingest in the morning comes back out minutes later. I also feel full and like my abs are turning into hulk abs. they cramp so bad that they stick out a couple of inches and sometimes even squeezes me making me vomit.
