Well i'm not Irish so it's not a day i really have ever celebrated other than when i would be in a bar and someone would bring it up and i'd try and get into the spirit of it even though i couldn't of cared less...never got the special days stuff i drank, did what i wanted and 'celebrated' most days?!
I'll be doing the same to keep sober as i did yesterday which it sounds like you are doing too!
Keep going Kjell, it does get a lot easier and things like this won't even cross your mind anymore, you just won't be that interested...unless you are Irish and then maybe eat green pad thai curry for tea hehe:-)
