Help

I seem to talk a lot about Roscoe's (lack of) sleep.  Although, considering how life altering it is for me, I don't talk about it all that much.  But I am desperate.  I need help.  If he doesn't sleep better soon I think I will give in to the temptation to crawl in a hole and hide for a few months.  I have slept a grant total of about 3 hours in the last 2 nights (yes, that is both nights combined) and I am so tired I can barely function.  I know, it is part of having a baby, but still at 10 months?!  The to-do list in front of me is blurry and moving and I am completely apathetic about getting any of it done.  The last 2 nights have been extra bad (i.e. he basically only takes 20 minute breaks from crying here and there - the non-crying time is spent nursing), but even on a "good" night these days no one gets much sleep.  This would be typical:

7:00pm-8:00pm Try and put him to sleep.  He finally calms and stops crying and falls asleep
8:45pm-8:55pm    Wakes up, repeat cry/soothe/cry/nurse routine.
9:45pm-10:00pm    Wakes up, repeat cry/soothe/cry/nurse routine. Give up and try go to sleep, too.
11:30pm-12:00am    Wakes up, repeat cry/soothe/cry/nurse routine.
1:30am-2:00am   Wakes up, repeat cry/soothe/cry/nurse routine.
3:00am-3:30am  Wakes up, repeat cry/soothe/cry/nurse routine.
4:30am-5:00am  Wakes up, repeat cry/soothe/cry/nurse routine.
6:00am Ray wakes up.  Roscoe restless, but I try and keep sleeping/resting until 7:00am


Seriously.

What the EFF do I do???

Obviously, he is not hungry when he nurses, he just wants to be soothed.  And obviously if he had his own room and my in-laws weren't a stone's throw away sleeping (and have to work the next day) we could let him cry more and soothe himself.  But that is not an option until we move.  SO... what can I do?  Any suggestions?  Here is what we have tried:

Crying longer before soothing
Chamomile tablets
Teething tablets
Tylenol
Baths before bed
Only sleeping in his crib
Sleeping in our bed
Ray trying to soothe him at night
Giving him a bottle at night instead of nursing
Pacifier
Sleep Sheep
Glow worm soothing thingie
Giving him a "lovie" monkey
Putting him to bed earlier
Putting him to bed later
Feeding him solids right before bedtime
Not feeding him solids before bedtime
Fan on

What else should we try?
