How do you get through withdraws faster? i think she is useing meth or ice

No good answer: She's got a big problem and it's going to take a firm hand from people who care. Withdrawal from stimulants doesn't typically cause cramps and the like. It's usually a matter of dealing with craving and for a while a strong need to sleep. Once used chronically there are permanent brain changes that make the urge to use persist. Stay away from users and losers or fail!

Med detox.: Detoxification should be done under close medical supervision. I recommend that the female in question work hand in hand with an addiction specialitst. Take care.
