There is a need to integrate the use of vitamin supplements into our daily way of life. Most doctors say that effect of taking vitamin supplements can only be felt after three weeks. Outside vitamins tend to suppress the in-built compounds inside the body. Therefore, it would be prudent and wise to take vitamins for three weeks and then stop taking vitamins for another three weeks so that the body gets time to adapt to any exogenous supplement.
I was a smoker just like you and enjoyed it very much. I did care regarding the smell or my teeth. I came to the point were I had to actually replace 8 of my teeth because of smoking. This was my the first time I understood I had to quit. 3 years later I am clean, healthier, smells better, and know that any one can do the same as I did.
