Can serequel make you feel extremely weak as well blurry eyes anxiety muscle tension and body tics. upped dose for sleep and began getting symotoms?

Yes: Seroquel (quetiapine) can cause all of the above symptoms (although I don't know of it causing tics). I also think you have hit upon the reason as well; in general it is not a good idea to increase a dose abruptly or to increase without first consulting your physician/NP. The higher dose is most likely what is causing your increased symptoms.
