Not Feelin' It Today

I headed out the door for a scheduled 4-5 mile run and after about 1 mile, I just wasn't feeling good. I decided to turn back and head home after 1.5 miles. On the way back I felt so sluggish that I walked for some time. Not sure if it was the benadryl that I took before bed, but I haven't felt so sluggish in a long time. Hopefully I can shake this funk today and back at it tomorrow.
