Haloperidol worsened tic disorder and anxiety. What to do?

Hi doctor,

I suffer from a Tic disorder since childhood with eye blinking and shoulder movement. It was not a big problem for me in my childhood. After marriage, it became worse with continued coughing. So I decided to take medicines by consulting a psychiatrist. The doctor prescribed me Risperidone and it does not help me. Then he suggested Haloperidol and it worked for me. My tics went away and my performance was back in my foot. But I do not have much energy and felt sleepy with a low-sex erection and premature ejaculation. I am taking Haloperidol 1.5 mg twice a day for the last three years. I decided to cut the dosage and now I am taking 0.5 mg once a day. But I have slight tics with a feeling of anxiety and dizziness at night. Last week, I went to the psychiatrist and he suggested me stop taking antipsychotic medicines. I have general anxiety and it makes the tic bad. He prescribed me Dozap 25 mg for five days and told me to take 50 mg for the next five days and 75 mg for the next month.
