Although I have been taking Seroquel for a while, I noticed that ever since I reached 600 mg, here and there I start experiencing a particular problem with dizziness. Sometimes in the middle of the night, I will wake up to use the bathroom, and my heart will race, I will stagger down the hall from the dizziness, until I get back in bed and pass out. Another scenario that happens sometimes when I get up, once again, my heart will race, and I will feel almost like I will faint. It usually won't last for long (maybe gradually improving over the span of a half hour) but this is especially troublesome if I need to drive somewhere that day.

Once when I felt that way, I happened to have a follow up with my Primary Care doctor, and I did happen to have a somewhat low blood pressure reading, so it makes me wonder if it's the Seroquel when it comes to that too. The nurse asked me if it is usually low, but it's usually more in the middle range for me.

The worst time I can recall was when I had to drive somewhere an hour and a half away. I was dizzy, and I know it wasn't smart to drive, but it was my only choice (work meeting). A woman I worked with noticed I was dizzy and gave me water. I felt faint and needed to sit down. It took a couple of hours to feel back to normal. It had been about 3 weeks since being on the higher dose that particular day.

Now, I experience the heart racing and feeling of being faint at least once per week, but luckily, only in the middle of the night lately, rather than a time where I must drive (though I do get a little woozy in the morning, not too bad lately, knock on wood). I have been on the higher dose for a while now, so I can't blame it on my body adjusting. Like I said, it only happens here and there, but it's enough where I am starting to have some concern.

Have you experienced this before? Did it go away with time? Does anything help alleviate this side effect for you?
