ULTRACET NON-ADDICTIVE??? YEA RIGHT!!! Just like Xanx was suppose to be non addictive when it originally came out. My husband has cronic back pain and ultracet is one of many drugs he's taken over the past 20yrs. Ultracet is one of the most addictive drugs he has taken. The Side effects of the drug is no walk in the park either! His side effects include: sleeping on 2hrs per night, confusion, pain in arms & legs, tremors, not leaving the house and extreme weakness. When he tries to quit taking it he becomes an emotional disaster!! He trembles, becomes extremely paranoid, cries and hurts. RUN FROM ULTRACET!!!!!!! COMMING OFF THIS "NON-ADDICTIVE, NON-NARCOTIC DRUG" IS HORRIBLE!!!
