Why do i get severe headaches?its been almost two weeks that i stopped smokin, then why am i facing this?

Nicotine w/draw: Try some head-ache meds. May be nicotine withdraw head ache too. If continues, despite meds and does not get better soon, see a dr. For other causes, unrelated to quitting smoking.

Nicotine withdrawal.: The headache you're experiencing could be typical of withdrawal from nicotine. This could last several weeks, but should subside with time. Don't go back to smoking!! Ride this out - if it worsens more than improves over the next week or two, visit your doctor, though.
