I'm curious about what side effects you experience with 25 mg Seroquel? I've never taken less than 50 mg of Seroquel or Seroquel XR ever. My current dose of Seroquel XR is 600 mg. I sleep well on 600 mg for about 7-8 hours. In the very beginning, I had a "hangover" in the morning, but no longer do. My Seroquel XR dose goes between 450-600 mg, depending on my mood state, but Seroquel XR is used for my moodstabilization along with Tegretol XR and Lamictal, not just for sleep. I have only minor side effects from these doses. Nothing to complain about much. Sometimes one has to wait out side effects to find that over time they calm or even go away. I, personally, find Seroquel XR to be a better choice for me than regular Seroquel in many respects. Seroquel XR does not have any dosage lower than 50 mg. Cutting it would defeat the "XR" purpose.

Though not a pill, when I have more stubborn insomnia, I am often really helped by my sound machine. Some people may brush off this idea, but I'm really serious about it. It has ZERO side effects.
