Hi, I have been vaping about a week and a half. I'm still smoking only about 2-3 cigarettes a day. I can't believe these things are working for me. I'm so thrilled and hopeful to be able to quit, finally after 27 yrs. I however, in the last 2 days have been experiencing a dizzy sensation, weird brain-wave like sensation, is the best way I know how to describe it. Has anyone else experienced this? Now I know that after 27 yrs. my body has to adapt. Is this part of the withdrawal? I really experienced them last night after walking briskly for about 30 minutes. I'm also concerned about this weird cough, I've developed. It's almost as if I'm coughing more since I've quit.Thanks for any input on this.
