Risperdal and diagnosis

my 16 and a half year old son was put on this medication because of his temper; however he sleeps excessively, does not have a problem with libido and is still as angry as he was before being put on this medication. His diagnosis had something to do with his oppositional attitude?? But isn't that fairly normal as well as common for a teenager who does not always get his way?? My ex husband had him put on this medication so that he would be easier to deal with. I want to get my son off of this drug. He is still taking wellbutrin which I dont believe has the same adverse long term affects. What do you think?? A concerned mom

MY BOYFRIEND HAS BEEN ON RISPERDAL SINCE THE END OF NOV.. HE WAS MISDIAGNOSED AS HAVING SEVERE DEPRESSION WITH POST STRESS SYNDROME. AFTER SEVERAL VISITS TO THE HOSPITAL, HE FINALLY RECEIVED SOME POSITIVE HELP. HEWAS SENT TO A OUTPATIENT CLINIC, AND RE-DIAGNOSED. THE NEW DIAGNOSIS WAS BI-POLAR WITH PERSONALITY DISORDERS. AT THIS TIME HE IS NOW ON EFFEXOR 150MG, DEPAKOTE2000MG, ZYPREXA5MG, TRAZODONE50MG, AND BENZTROPINE1MG AND RISPERDAL1MG. I SEE SOME POSITIVE EFEECTS HOWEVER HE IS EXPERIENCING WEIGHT GAIN WHICH WAS NEED. AFTER READING SOME OF THE POSTINGS QUITE FRANKLY I AM AFRAID THIS CAN TURN INTO A NEGATIVE, BECAUSE HE DOES HAVE TROUBLE SLEEPING. GETTING TO SLEEP IS DIFFICULT AND WAKING UP IS EVEN MORE OF A PROBLEM. HE IS ALSO HAVING CONSTIPATION. CAN ANYONE TELL ME IF THIS SHOULD OCCUR FOR THIS AMOUNT OF TIME? IF THIS DRUG TAKES TIME HOW LONG DOES IT TAKE TO WORK EFFECTIVELY? HE WILL SEE HIS DR. WITHIN A COUPLE DAYS. IF ANYONE READS THIS AND HAS BEEN ON THE DRUG FOR ATLEAST SIX MONTHS CAN YOU PLEASE RESPOND TO ME WITH ANY HELPFUL INFO.
