These situations started me down a very slippery path. I think you are noticing you are having a problem with the number of drinks or how your drinking habits have progressed. That's a great concern to have this early in the game, as most don't figure it out before it is too late. Should you quit drinking? That decision is yours and yours alone but you need to certainly be very aware of your tendencies and how your drinking has progressed. Why not take some time off from drinking and see what happens?
