It's my own fault.
For Lent I decided to give up the alcohol. I really love my vino and my margaritas, but I should really be concentrating on my training. The last couple of days, or what seems like weeks, has been emotionally and physically draining. By yesterday I was going crazy and NEEDED a margarita. And I got one. What I've noticed as I've gotten older, however, is that although I enjoy wine and margaritas, anymore they make me sick. Not barfing sick. Sick as in no matter if I drink a little or a lot, I always wake up with a headache. And today was no exception. So, maybe I need to go back to no wine and margaritas.
What have you noticed as you've aged (like a fine wine) that you can no longer do or have?
