Yes...stay on the juice bro. Your cold will subside. It may not be Sust flu. Usually when I start my test I get chills, light fever and a general feeling of just not feeling well after the SECOND shot. I don't get a sore throat or sniffles. If it is due to the sust, it should be over in less than 2 days. If it's a cold...7-10 days. Just train light and eat as much as you can.
