Swims new addiction! Help and advice needed

[BumpBump]

Swim has been using benzo's for a couple of months. He uses them for recreation not for any medical purpose. He took them for a couple of weeks solid in the evening then had a week off and felt no ill effects. So swim cut down to once evrey 4-7 days depending on his week.

Swim has been taking xanax and diazepam often combined. The last few times swim has used xanax alone and spaced it out 5-7 days.
Swim has now got withdrawl symptoms.
Mainly numb fingers and toes and fatigue and generaly feeling pissed off.
Today swim had bad stomache pains, and diarreah. Swim is not sure if this is a bug or related to the withdrawal symtoms. He is feeling very cold also.

Swim has been 6 days now since his last xanax, and previous it was 9 days then swim got on some opiates and ate one! Today has been the worst yet. Yesterday swim was fine. He seems to just seems to have a bad period over an hour or so then he don't feel so bad.

swim can handle the withdrawal, even though its not nice its tolerable. But should swim take some valium when they get like this?

If swim manages to take a couple of valium and waits a week, then less valium say a week later and day later would this make it easier? If it will just string it out and possibly make swim worse in the long run he will just put up with the symptoms.
