I Have Noticed Over The Past Year That I've Had

I have noticed over the past year that I've had sinusitis, it always feels like my nose is stopped up, and very bad fatigue and I'm very fidgity. I can't sit still for more than 5 seconds unless I'm laying down, but I'm perfectly healthy. Could smokeless tobacco be the problem? I've been dipping for 4 years I'm up to 2-3 cans a day now.
