4.5 months and moving

I was a ridiculously heavy smoker for 15 years. I decided it was time to stop and had some horrible withdrawals. At about day 90-100 I began to feel better. Sleeping well and feeling more myself. Come three days ago and a wave of paws hit me. Mainly headach, dizziness, and some slight nausea. What makes me happy is knowing that I am getting better. The waves are spreading out and the symptoms seem to be getting a bit easier. I know everyone is different but what makes this great for me is knowing I got blood work done and checked up. Everything came back clear. If anyone is having massive anxiety I would recommend getting checked out to ensure everything is fine. Once we find out we are good and it is truly paws it brings some ease to the entire situation.
