I am on Lamictal as well (250 mg), and it is working nicely, in conjunction with Effexor (225mg) for the depression side of BPD.

Up to a month ago, I was in really bad shape in terms of sleeping. I was consistently getting 2-4 hours a night, some nights 0. At the time I had a choice of Melatonin or Trazedone and tried both many times. The melatonin made me slightly drowsy, but not enough to put me out. The trazedone worked too well, and I'd sleep for up to 16 hours. I tried relaxation tapes with both of those, which worked a bit.

Now I'm on Ambien, which is working great. If I take it around 9:00, I'm asleep by 11:00 and I'm able to get up and going by 6:30.

My advice for moving may be offbeat, but its worked for me for my past 4 moves. I buy something for the new place, and that helps me feel like the agony of packing is a little better. It doesn't have to be something expensive. I've bought things like new rugs and shower curtain for the bathroom or cool curtain rods for my bedroom...

Best Wishes for your move and finding the right sleep aid.
