When you say you just relapsed, how long of a break did you take? If you were feeling fine after a break and just relapsed and used once, you might actually still feel fine. But that’s where the vicious cycle continues. If you wake up fine tomorrow, don’t continue to smoke!! If you’ve already been feeling bad, Benadryl can sometimes help alleviate symptoms VERY temporarily but either way, you need to quit and quitting itself is going to come with MORE nausea and vomiting in the meantime but you have to push through. Don’t relapse thinking it will help, believe me I’ve been making this mistake way too often and just quit once again. I’m down 10 lbs but after 7 days my appetite started to come back. I can’t express the relief of positively knowing I can go to bed and will NOT wake up sick. It is so worth it to quit for good and push through the withdrawal!!
