raggie,
Well. all three can have very similar side effects, including sleepiness, weakness, difficulty concentrating. Trileptal is usually used for seizure control and if you have a seizure disorder, Seroquel can potentially increase the risk of seizures. It is used in people with seizure disorders, but they should be watched carefully, especially when they are first started on it.
The good thing is that most people get over the side effects of the drugs within a week or two of starting them.
