Movement disorder. So please guide me.

. I am suffering from movement disorder from last 8-10 years that is sometimes (not all times duration between 2 attacks may be alternate day to month to years) I have to move my limbs in awkward direction rapidly. It (involuntarily movements) can affect all my body parts including head which is worst. I feel so much pressure/urge in my head that i have to rotate my head clockwise/anticlockwise. All these are temporarily suppressible. My stress is manageable. Sleep is proper. No family history for this. No drinking, no smoking. No Fits, Convulsions. CT Scan/MRI Scan/EEg Normal. I have consulted Neurologist and was told that this may be TICS and prescribed REVOCON (TETRABENZINE). But this is not helping me. So please guide me....... Thanks
