I don't know! I assume there is something in 2nd hand smoke that we pick up on enough to know that it will help. But nobody could answer while I was running around desperate to smoke. I am so glad that I'm not the only one (although sorry you've been through that before because it sucks).

The other alternative at the time was that I gave up caffeine completely around the same time and that it might have been related. But I don't see how. I truly think my body wanted cigarette smoke, however it knew that.
