Oh my good sweet Jesus I have so, so much to say I don't even know where to start.
GetOrf I clicked on this thread because I tend to read anything with bipolar in the title and did the most massive double take when I saw you were the OP. I'm so sorry. It does kind of suck.
First of all I am glad to see and think it's fab that you have not lost your wonderful sense of humour.
I'm bipolar too and it nearly meant the end of my life at one stage. More about that later, but I was diagnosed in 2008.
I'm on 500mg of quetiapine and 1200mg sodium valproate daily. It did take a while to get my meds right. I take most of my quetiapine at night because it does knock me out. The tiredness and impact on blood pressure (already have low blood pressure and it lowered it even more to the point where I fainted once or twice) have lessened.
Here's the important part: I have been completely, 100% myself since 2009. That is four years of gorgeous stability, going through life's normal ups and downs, no depression, no anxiety and no mania. It's awesome. I came so close to losing everything and now I have it all. I went back to work in Jan 2010 and have not had one single day off because of my illness since then. Well, apart from keeping appointments with my CPN or psychiatrist. My therapist and our marriage counsellor we saw outside working hours.
Advantages of the meds apart from keeping you stable: you gain weight (advantage for you, not for me. I'm almost as tall as you but I weigh, um, 17 stone), you sleep really, really well and I swear my hair and nails are nicer 
I keep careful track of sleep, I take my meds religiously, I only drink to excess sometimes, I'm careful with jet lag, I talk to people about stressors.
Ok enough of an epic post. I'm going to PM you.
