The MS does interesting things to the "outlook", so to speak, like changing your appearance. I have recently put on alot of extra weight, mostly related to a new med that increases the appetite expotentially. Some of my family members, however, relate it specifically to my penchant for Pepsi, which started in childhood. So recently, because the weight is affecting my ability to move around, I have given up Pepsi and replaced it with grape juice. Wish me luck!
