Careful with the xanax, yes it does help with withdrawals, but taking more of that can lead to the same thing as the perc w/ds....only take if absolutely necessary
16 days insn't very long but 20 a day is a large amount. Is that the number you were perscribed by the doc? Do you ever take more then perscribed of the xanax and valium? Good luck I hope all goes well, if you haven't had a problem in the past, be careful and don't end up like so many of us!!
you should have very minor wds if any for 16 days...maybe a little tired feeling.
w/d's last bout 5 to 7 days. You can take valium but only at night to help you sleep and only for about 4 day or you will be back in the same boat you are trying to get out of.
How many are you taking? 16 days not very long you should w/d quicker
