Yes, Pasley was right that I was overweighted. I was struggling to get down, so had added more weights, but all I really needed to do was RELAX, and keep my arms/legs motionless like he said. I went diving this past weekend, and did it perfectly. Sunk like a rock because I was still overweighted, but was advised to keep the extra weights to compensate for an emptier tank later in the day. I dove with 12 lbs in fresh water, and I think I could have gone with 8 or 10. This coming weekend, we are diving again, and I will try 10. I understand about needing more for later in the day, but 12 was too much as when I did my buoyance check I sank under the surface about 2 feet. I would rather have had the correct weights when beginning, and added more later. Our dives are not lengthy or deep ones, and we will use the same tank of air for the whole day, or at least last weekend I did. So it would be easy enough to grab a couple more pounds from the boat prior to a 2nd or 3rd dive.
Don, I'm working on it!

And I have been "refreshed," as I sat attentively through the OW instructional a couple of weekends ago when my son was doing it, and then last weekend got back in the water with my instructor for a couple of dives. I'm hoping to not let it go so long between dives this time, but with winter coming in the midwest, and no tropical trips planned until April, that may not happen.
DH and I are taking Peak Performance Buoyancy as part of our AOW this weekend, and I'm sure that will help me even further. Simple practice, and more dives as you said, will help.

But having only 9 dives under my belt since certification, I'm happy with where I am now, after this past weekend. Unless we move to the beach, I doubt I'll ever feel like I'm "advanced." That's not the point of our taking the AOW; it's simply to continue our learning and get more practice.
crpntr133, thanks for your comments!
I tried to view the videos on the link given yesterday, but no luck even after d/ling QT. I'll try something different today. Thanks!
