Hello I've extracted Codeine from pills with 240mg Aspirin, 200mg Paracetamol, 50mg Coffein and 10mg Codeine. In total I have 150-200mg codeine and how much Hydroxyzine(Atarax) i need to use? Bcs I dont have prescription for Prometazine but for other First Class Antihistamine that is weaker(Atarax). And Im not sure how much to use. One pill Atarax is 25mg. Should I use 4-6 pills to make them 100-150mg Hydroxyzine?
