why do mornings still suck?

I eyes creeped open this morning.  My head was already pounding.  Ughhh it's morning! not again:( It feels like I drank a fifth of cheap vodka last night.  Why does my mouth feel like sandpaper?  Quick scan of last night, are chicken and peppers for dinner, went to the gym for yoga and sauna, drank 2 bottles of water, took a shower, went to bed.  No remembrance of drinking.  So why do I feel so hung over?  I feel like all I do is drink water! Maybe my kidneys are still getting used to the new water flow?  I'm not sure, whatever it is, my mornings still suck!  Hopefully tomorrow will be better!
