I can relate to the wallet being fatter, I estimate ive saved around $150 in just under two weeks, couple of months like that and I can buy a MacBook Pro lol.
The only physical change ive seen so far is that my eyes look brighter, I looked in the mirror a couple of weeks ago and the person staring back the eyes just looked dull and lifeless it was one of the main contributing factors for my ongoing attempt at getting sober.
Im hoping to lose weight but it hasn't happened so far!
