Hi Vinnie,
I am in a very similar situation as you re. clients, summer coming, wife & kids. A few things I tell myself:
Right now, don't worry too much about the future - eg. clients, better weather. You can build up your strength to deal with those days when they get here.
Don't buy into the illusion that a couple of beers with friends will be this great experience. It likely won't be a couple of beers anyway & even if it is, the obsession will be back and will lead to another major blowout.
Going to bed sober and waking up without a hangover or any guilt will be the great experience. Really think about this - how will you feel in in the morning if you drink compared to if you stay sober?
Being there for your wife & kids is your responsibility - it's okay to be cranky occasionally.
Keep busy - get through the day, work on your recovery, play with your kids, fitness, TV - anything but drink.
Wishing you the best. D
