I've pretty much drank the entire time I have been on atkins, since March of this year. I only drink Burbon with water/club soda, so there are no carbs in what I drink. Most days I don't drink, but when I have, most times I have only had a couple, and a couple of times I let loose and had a bottle.
It may have slowed me down for a day when I had alot, but I was always in control, so I never ate things I shouldn't have when drinking. I think that is the more dangerous problem with drinking on Atkins. You get a little drunk, and start diving into the Nachos.
If you can keep youself under control, and not eat bad when drinking, you should be fine. Of course, everyone is different, and if you notice it hurting you, you should definately stop. It hasn't hurt me (60 lbs since March 9th), so I haven't stopped, but you may be different.
Also, try to stick to unflavored sprirts, and water/club soda as a mixer. Flavored vodka/rum can have added carbs because of the flavoring, and too much diet soda can be bad for you.
