@LaZeR - Forgot this in my previous post, to help explain why I mentioned those chemicals in smokes.
I'd pretty much been like the Energizer Bunny all 42+ years I smoked. I could work outdoors 8 hours in our Florida heat, stay up until all hours of the night, etc., and rarely if ever felt tired. But within about 6 months of my totally quitting...I was gaining weight, my energy level was noticeably declining, and I was taking naps that I'd never needed.
My endochronologist told me that quitting smoking definitely has an effect on metabolism. Not getting the chemicals from the cigarettes that I smoked for 42+ years had definitely affected mine.
Have you seen your doctor and/or had any bloodwork done recently? If not, I'd recommend it. Better to have something checked than to just ignore it and let it go.
I was a hummingbird all my life. Worked swing shift while raising two little kids and doing a total rehab on the house (while living in it).
Long before I quit smoking, I suddenly fell ill. Felt like the flu. I hurt all over and was too tired to move. One day I was fine, the next I couldn’t get out of bed.
Long story short, after a couple years of testing I was diagnosed with fibromyalgia/chronic fatigue.
Which is no picnic, but when my husband suddenly didn’t feel quite right, he was diagnosed with cancer.
So I agree with you. It could well be a side effect of quitting, but it could also be something else.
Better safe than sorry, get it checked out.
