I went on Atkins some time ago, and lost a lot of weight. Having done so, I figured it was finally time to stop smoking.

I did so 3 months ago. Gained mucho weight from stuffing my face. No that i'm confortable with not smoking, I've been back on Atkins for 2 months, and haven't lost an ounce.

Nothing has changed except the smoking. I used to lose an average of 3 lbs a week. Now after 2 months, I think I've lost maybe 5. I'm a long time lowcarber, and I'm not cheating, and am eating the same as I always have. Only difference is the lack of 2 packs a day of cigarettes.

Do I have to get more drastic with the carb restriction now, or will this pass eventually?

If you've lost 5 pounds in 2 months, you're still losing. Accept it, even if it's slower than you anticipated.

I quit smoking in January, and "allowed" myself to gain some weight to get over the smoking hurdle. After gaining back a whopping 20 pounds, and having a cigarette setback, I'm back to strict low carbing, no smoking, and losing, but very slowly.

Whether you quit smoking or not, there are times when the body slows down and we don't lose as fast as we want. Have you measured? Are you losing inches and not pounds?

Hang in there kiddo. What I see from your stats is progress. That's great!!! And you should be proud of it.

PS..CONGRATULATIONS on kicking the nicotine beast. That's worth waaaaaaaaaaay more than it's weight in gold. GOOD JOB!

Quitting smoking does affect your metabolism at first. It will slow it down until your body adjusts. The only thing I can suggest is patience.
