I have 100mg seroquel pills that are coated and they are very hard to split evenly without crushing them. The 100's are pretty small, the 25's must be tiny, are they coated as well?
I think feeling "odd" is as good a way as any to describe the initial effect when taking seroquel. I'm glad that you have tolerated it as well as you have so quickly given how sensitive you are to meds. I think that is a good sign

Have you felt any sedative effect at all?
I'm glad that you are working on being hopeful Mari
