My husband is addicted to percocet and has tried a few times to quit cold turkey. This time he has gone about 10 days without any pills (I think). For the past couple of days he has been extremely angry and doesn't want anyone near him. He says that he is angry and everyone and doesn't like anyone. He told me that everyone needs to just stay away from him. I am used to him having mood swings and being mean but not like this. Is this part of the effects of the withdrawl and will it get better with time? I have been trying to be supportive but it is really hard.
