Don't fret, a day sober and medicated is a thousand times better then a day drunk.
I suspect a great deal of the emotional swings we feel are our bodies adjusting to the lack of alcohol. In my longest stretches of sobriety I experienced less mood shifts as my body evened out.
Try not to let these ups and down engulf you. Recognized what you are feeling, accept it and know that it will pass. Sometimes that little practice will make me feel better immediately. If that doesn't work you can always hop on youtube and watch videos of goats yelling like humans or people slipping on ice. That always cheers me up.
