my nausea went away after three days
That's an unusual side effect from Seroquel. I did have it from Depakoate and lithium which is more typical but I tolerated the coated versions better so they didn't produce nausea. Seroquel might have that option as well. Seroquel has a short half life so perhaps the extended release version would be more of help. However, although it is approved for bipolar it was originally designed as an antipsychotic. I have schizoaffective and I require both a mood stabilizer and an antipsychotic. That's more typical. The mood stabilizer that worked best for me and was easiest for me to tolerate was Lamictal but each person responds differently to each medication. Speak to your psychiatrist about all this.
