Slow and steady wins the race. Just keep at it and everything will work out. You'll find that right balance between the cigarettes you love so much and keeping the sinus drainage in check.
By the way, the best answer you can give if people question you about why you're smoking, tell them you used to smoke and have been stressed because of work/home/money/whatever. Plenty of people go back to smoking in times of stress, so that will satisfy them if they question you.
Keep up the good work and keep us updated.
