coffee has allways relaxed me, and now i am getting sleepy. i am stopping at 3 cups

, as i do not drink much coffee regularly!
( well maybe as I leave to go home may get some more coffee in two hours, just have never had a coffee machine give it free. Of course it may be fixed by then lol )
I have been behaing my diet and not putting sugar in it, using sweet n low lol
i use equal at home, only work uses the pink packets
