If it's Sunday, I must have a dilemma

I've been offered a job. A very good job. A job that would give me a lot of very nice benefits as well as good mental challenges. Being the uber geek that I am, I've spent a lot of time with a spreadsheet listing the pros and cons of each company. I'm pretty confident that I've made my decision, but thought it wouldn't hurt to list them here too.

Company A
Pros
The team
A lot to learn from Sales Director and Group Sales Manager
Leave for September/October already approved
Close to public transport
Able to be flexible when necessary for appointments

Cons
Hate the way that I am feeling at work - seem to be constantly angry, frustrated, bitchy and cynical
Don't feel like I'm doing my job - always seem to be supporting systems, not doing what I'm paid for.
To grow in my career with the company means moving to Sydney
Very little support from Sydney - I have had a new manager in Sydney since the beginning of January and still have yet to meet him.

Company B
Pros
New challenges
Mentored into a management role by August
The team
Going back to more of a start up feel - have more input into systems and processes
Working with a legend in my industry (who I really like as a person)
My September/October leave will be honoured (and paid)
Close to public transport
Career Development without moving to Sydney
International support to deal with work when needed without staying back
Additional resources
Team has international experience - a lot of different things to learn

Cons
Have to establish myself in a new company
What if I suck as a manager?
How much extra will I be expected to do with a crackberry, or is it just for emergencies within specific times?
Not sure just how much flexibility I will have - a crackberry should do it though

So, what do you think? I haven't listed any salary or benefit options - I'm reasonably confident that my current employer will do anything they can salary wise to keep me, so I'm not factoring that in at all.

He sees you when you are sleeping ....

I'm concerned. I seem to be suffering from prophecy in hindsight. Way back in December, I completed a meme about icky Christmas songs, and pointed out the creepiness of Santa watching me when you sleep.

My sleep patterns have been all over the place for the last few years. I can function for weeks on about 4 hours sleep a night, or can have horrendously broken nights sleep - pick an hour, any hour and I've seen it this week. I can also sleep really violently - when I got up the other day I had to rescue pillows and beddings from all over the room, and put the rest of the mattress back on the bad. I'm not even going into my dreams.

To cut a long story short, I've been given a referral to a sleep specialist. They will be doing a sleep study on me. I haven't been able to stop singing "Santa Clause is coming to town" since. My big concern though - what on earth do I wear to be watched sleep? I'm not your nightwear kind of girl - whenever I wear it it tends to end up on the floor, so I generally avoid it. Any suggestions?
