Yipppeeee... so happy. I feel so much better too, though I now seem to have developed a hacking cough. Is this normal after 2wks?
Also, I have read many times that many people slip in week 3. Any tips and why is this? I have a friend coming over tonight who smokes so this will be a real test for me. She is really supportive though and will go outside to smoke 
Day 15 is fantastic, so you are starting to count in weeks rather than days that is a great feeling.
As for the cough, didn't happen to me but lots of people get colds, coughs etc just your body clearing out the rubbish.
Week 3 can be tough for some, same as 3 hours, 3 days etc. i didn't have a problem with week 3 (week 4 got me). you seem to be doing really well so all i can say is keep doing it, if you do have any problems reading and posting will certainly help.
Good luck and keep it going.
