Hey @atlantis1982 congrats for participating in the#veganuary challenge =) If you have any questions about being vegan we're here to help! I don't think your muscle soreness has anything to do with the diet. Most of us actually feel less sore, but make sure that you get your daily nutrients including protein especially before or after workouts. One I personally love is peanut butter sandwiches, and also protein shakes containing some vegan protein powder and oatmeal with a banana and almond milk =) Hope this helps!
