Yes it is, except for the pains in my face, the constant headaches and the elevated heartrate. And the dip hangover that I will wake up with every morning that doesn't go away until noon. AND, when I quit, I tell myself that I won't miss all that crap, but then a few days go by and I feel better, so I buy another can. Especially when I do yardwork. So, overall, I know it makes me feel like crap and is bad for me, but I need you guys to kick me in the tail to break free.
