If it's something you would log-transform the DV, you might consider
the following trick:

It works really well.

Then you could specify your ultimate model in xtmepoisson, which is
undoubtedly faster than gllamm. gllamm is kind of like trying to do
fine carving with a pocketknife. It can do a lot of things but it's
very generality makes it not so optimized for any one task.
