V.M. is a 34 year old female who is at your clinic for a follow up on her treatment of bipolar disorder .  When you enter the examination room she is pacing.  You invite her to have a seat and while she is sitting she is rocking back and forth.  While reviewing her chart you see that she is on haloperidol 5 mg TID.  You ask her how she is doing and she tells you that she feels like she has ants in her pants.  What do you think is going on?
