Yesterday I felt the beginnings of a sickness coming on. So I took medicine all day hoping it would go away and it didnt. So before I went to bed, I took my medicine. Only it was daytime medicine. I think I got a total of 3 hrs of sleep. So my word of wisdom for you is this: never take daytime medicine before bed. Ever! It will keep you up forever and ever and ever and ever. Ech!
