Whoo-hoo!
Now, do you mean a headache from the withdrawals of no nicotine, or do you mean when you were a smoker, you'd wake up with a nicotine headache?
Not for nothing, only a week into my quit -- and I'm thrilled for your loss of headache -- what struck me the most with your post was the fact you went to a party, had some beers and didn't smoke! So good for you
Gives me inspiration for what hopefully is around the corner
