Smoking analogs, I would cough some when I first got up in the morning, but this is an all-day thing. It's different looking "stuff" too. I know that it's a natural thing to do after quitting, and that it helps the lungs clear themselves, but I just don't know how long it lasts. I believe it also helps it along to drink plenty of liquids, I'm constantly drinking something all day. I never really had a "smokers cough".
Yes nitewriter. Water is very important when lungs are getting rid of crap. It's good for other reasons as well. The couch lasts different times for people depending. I haven't coughed but I did a lot with the COPD and analogs. Everyone is different. Also, could you have a bug or chest cold? Just keep downing that water. Aim for a gallon a day if you can. Otherwise a half. That really isn't that much if you measure it.
Hugs,
