Oh hang in there OP, you have a little way to go! I have been vaping since Halloween (quit smoking after 25 years!) I no longer hack my lungs up every morning. I sleep better, I have more energy now, food tastes better etc. My first 2 to 2 1/2 weeks, I felt kind of cruddy. I was tired alot, felt fluish etc. I know it was the shock to my system of giving up the nasty stuff in cigarettes. I got past that and started feeling wonderful!!
The biggest thing for "me" is my meds that I take daily are WORKING. I have said for a very long time that my body seems to process prescriptions different on me than other people. I have had trouble with pain meds, sleep meds and a couple other prescriptions. Well, they all are working great for me now! I ended up with more than just healthy lungs, my pain meds WORK and I am pain free now!!! That aspect has totally blown me away!
