Hey Welcome Stw.
60+ days is awesome and congrats on quitting smoking too.
I was very tired in the first months.... We all know tiredness leads to ill thoughts. Yes I was depressed and my mind was all over the place.... KEEP GOING !! ... It gets better,,, trust me... it gets better!
So hope you are resting ... Thing is .. Even if you are not tired. Give your body ample rest. It's a machine and with proper diet, exercise and rest you will be A-OK ..
Lastly, have you had a physical exam by your Doctor?
