Seroquel is definitely a powerful sleeping medicine.

At first, I was prescribed 100mg which proved to be way too much for me. I was falling asleep in class and it made me sleep for 12 hours, maybe more. We cut it down to 50mg, but for the last few years I've been cutting the pill in half because I felt that it was still too much. We're trying to slowly decrease the dosage, but I've found that 11.5mg isn't effective if I take my Adderall too late in the day. Playing around with the meds has made me learn what time of day is best to take them in order to sleep properly. The Adderall is best taken before 9am (I'm on 15mg XRs) and then I try and take the Seroquel a around 9 or 10.

About the heart palpitations, I've noticed a similar side affect. It's like your body feels slow, and you can feel your heartbeat heavier than normal. Does that sound familiar? It's an odd sensation but I've come to accept it. It has the ability to change your blood pressure which can be scary. The side effects were a bit of the reason I wanted to lower the dosage.
