My father in law was taking high doses of clonazepam (up to 8 a day of the green I think 1mg) and seroquel ( up to 2,000 mg a day) and he s made the desision to withdraw himself off both at the same time to lose weight and just to be off medications. He refuses to go to a hospital so we are trying to treat at home for the last 2 weeks but are getting more worried of his condition each day. He was doing ok at first but for the past 3 days has been declining. He will not eat, there is memory loss slightly, extemely agitated, severe cramps in legs, ams, and stomach, slight slurred speech, and all he will take in is water. He is 352lbs and 60 years old. What could happen in the process of this withdraw and will he need to be hospitalized?
