probably returning to the er wouldnt help unless you get full blown manic.Chances are they would either give you something else to try or admit you.
Dont take anymore of the script if your really reacting.
Ativan is what i take when I think im getting hypo/stressed.Ive talked to my pdoc about dosage because his first script,dosage didnt do a thing for me.He told me to take another if im freaking cause i tend to self medicate other unhealthy ways.Thats not to say that you should take more.Just see your pdoc right away or if you cant see your gp.
Good luck keep us posted
Perscriptions are not anything to gamble on.
