Well, I have been enjoying the little steps I've taken with my pipe. I've gone very slow. And felt accomplished when I finished my bowl. Perhaps I was feeling too confident. Yesterday I decided to smoke and used a blend with less nicotine. Some 40-minutes later, I wrapped up and went bout my business. I felt a little dizzy and periodically slightly nauseous. I wondered if I smoked too fast, but the bowl wasn't hot. And believe it or not, I have not experienced tongue bite. I've gone that slow since I started smoking a pipe. But this last one was not pleasant and lingered for a time. Is it normal to have smokes that backfire like this? And what can I do to prevent it? Thx for your support.
