I take vitamin D for my SAD 5000IU and a Vitamin B12 sublingual. I've also found rescheduling my get up times to doing some cardio early in the morning, taking a little walk at lunch to get sun, and then following an evening workout with about 15-20 minutes in the sauna helps big time. I won't lie that one of the hardest things about this breakup is also dealing with the sudden cold! IN the past I've actually put a countdown to spring on my fridge but now I'm trying to just fill the days up as they are so I'm not letting myself get lost in the weather. It's tough though sometimes - am definitely having a hard time getting moving this am.
