stinken vitamins

 So I found out today that I am NOT getting enough vitamins, which is causing the sides of my mouth to split open. It is so painful, it feels like papercuts and everytime I talk or open my mouth to wide it reopens the cut. I hate forgetting my vitamins in the morning! I will have to make a note and put it where I will see it every morning, telling me to take my vitamins. I have my next check up on the 21st of July. I am so nervous to weigh in, I hope I have lost weight. I dont really feel like I have ,but maybe im the only one that cant see it.
