Is 50mg too much for a first time dose ?

My doc prescribed it to me for CHS (a type of cannabis withdrawal syndrome) symptoms I have been dealing with like waking up in the middle of the night having panic attacks and having moderate to bad anxiety problems in the morning hours. After reading some of these posts here I think she may have gave me too high of a dose to start off with . I’m taking it tonight for the first and she also prescribed me clonidine .1mg twice a day as well which I’ll be starting tonight. Anyone else taken 50mg and if so what effects did it have on you ?
