I quit smoking about 10 days ago. No serious problems quitting after being a smoker for 30 years. Then a couple of days ago, from nowhere, I had a full blown melt down panic attack. Thought I was dying. So bad I went to the emergency room. Had no idea what was going on. Doctor admitted me and ran a bunch of tests, and found no problems. I got home and I'm still feeling like I might die any minute. Haven't smoked yet but I needed to reach out and ask if anyone else has had such a huge reaction to quitting. I feel like a wreck.
