Well,
@lostforgottensoul - it does sound like there are meds you maybe haven't tried. The reason I'm asking is because everyone responds differently, within the zone. Seroquel will dampen your anxiety, but it's likely you'll need to get up to around 300mg/day. That's a working dose.
Whatever you decide - you need to give it a complete trial. If your doc suggested that you'd need to up the dose, then add the addl 50mg in the AM now. If you want to wait, wait the full 7 days and then go up. (I'd be very surprised if you did not need to go up).
Seroquel works. It will slow you down, and that will diminish your anxiety. Honestly, it's not going to do that at 50mg. You'll get better sleep on 50mg, that's it.
You might want to consider asking about the other mood stabilizers and atypical antipsychotics. Also Effexor and Lithium. Basic SSRIs ('antidepressants') are often ineffective.
I know you're on a bunch of other meds for pain stuff, and I'm guessing there are interaction challenges, so your menu might be limited. Just remember that you won't know if something is working for at least a month, really - and that's assuming a titration period. Judging on how you feel after a few days is just not possible, medically. You need to reach peak concentration in your system, which takes many days. Some are faster, some are slower - but a week is the absolute fastest.
I know how frustrating it is - been there, bought the T-shirt - but there's no shortcut.
