werewolf

Okay iam curious and a bit nervous about casting the werewolf spell upon me..dnt get me wrong iam nt scared of the side-effects that comes with it..its just that will i be able to transform at will and not when iam angry or excited.

There's nothing to worry about as no spell reputed to turn you into anything other than the human that you already are is going to work. That's why spells such as ones that claim to turn you into a werewolf or a vampire are in the fantasy section. You cannot turn yourself into a werewolf by magic or by any other means.
