I assume you're not inhaling.............
I believe the body reboots itself every now and again. People get colds that live in Florida and people who live up north go outside in a soaking wet towel to get the newspaper but don't catch a cold or pnuemonia.
People take vitamins like they're going outta style and get sick and people who smoke cigarettes don't always die from lung cancer......
I just think, you're body is changing the oil. Wait it out bro.
