Prozac and Involuntary Muscle Twitching?

I am taking prozac since 2 month and now seemed to develop a form of restless leg syndrome and muscle twitching. The restless legs are the worst in the morning, but my husband told my I also move my legs a lot in my sleep. I also developed some muscle twitching in my legs, arms and stomach. Are those common side effects of prozac? Should I try taking some vitamin or iron supplements? Are iron supplements save to take with prozac? I tried making an appointment with my doctor, but can't get a soon appointment.
