I just started to take ctyo gainer a few days ago, a product made by Muscle milk. I have been talking regualr whey protein for about 5 months now with no problems. When im finished drinking cyto gainer, right after i get super tired. It happened yesterday as well as today again after lunch. So tired to the point i passed out on my bed for about 1 hour. I wake up feeling like shit and kinda dizzy/hung over. I dont know if im getting sick or if this is a possible side effect from drinking this?
