Trust me, today was my first day at work this week. Monday and yesterday I was under a pile of blankets sweating my butt off yet felt like I was freezing to death and more aches and pains that I would want even someone like Street Wolf to experience.
I still didnt get really clear headed until a bit after lunch today. I had not ate anything since late Sunday until yesterday evening and even then it wasnt much.
Monday morning, I drove to work, took me an hour to get there, I drove with the heater on full blast and still never felt warm, stayed an hour at work and then told the boss I like my job, but not this much and I went home and just made it back today.
So I feel your pain.
