i've never heard atenolol,it may work lihe clonodine.Clonodine is fantastic,it takes away that heart pounding and really helps with withdrawal.i dont like when doctors are stubborn.it's almost like they want to see you in dis comfort
its basically the same as clonodine. (IMO you should be really careful with this stuff)
From what I have read atenolol is mostly used for alcohol withdrawal.
Maybe someone who has used it will respond
