How long have you been seeing him? Most psychiatrists that are in their own practice do only spend short periods of time with patients. Then they have counselors in office that do longer therapy sessions. My psychiatrist, I only see for about 10 minutes or so but I also see a counselor there.
I would suggest calling his office and letting them know how your feeling, see if they will do a med change over the phone or if he wants to see you sooner. You always do have the option of changing doctors but in the mean time it wont help your symptoms now. Also, have you have a physical exam with your regular doctor? Have they ruled out any type of medical problems for what your feeling physically? I'm not saying that depression wont cause that or the medication combination but just to rule out everything.
