Just googled "What happens after 21 days of quitting smoking?"
Answers: Your circulation improves. Walking becomes easier for you. Your lung function increases up to 30 percent. Insomnia "Brain acetylcholine receptor counts up-regulated in response to nicotine's presence have now down-regulated and receptor binding has returned to levels seen in the brains of non-smokers."
Whatever the fuck that last one means... let me tell you the Lindsay breakdown of what happens after 21 days:
1. Urge to smoke increases when surrounded by assholes 2. Brain functions like a total and complete psycho that thinks about nothing but smoking 3. YOU GO FUCKING INSANE BECAUSE YOURE SO SICK OF EVERYONE DOUBTING YOU ALL THE FUCKING TIME. 4. You start a blog and realize no one's really reading 5. You start a blog and realize this will be the longest year of your life.
