@Molly3,
I attend a lot of conventions; I like them. I always have.
Mostly, I go for the speakers,
but I 've had too much trouble remaining awake
for lectures or shows in which I have great interest,
and not having slept long enuf in my hotel suite the nite b4.
I 've been advised to take
MELATONIN to bring on sleep
when I want it. I got some, but I have yet to test it.
I heard that it is also good against anxiety.
