I have high functioning autism but i feel an urge to make weird sounds? is there a drug for that?

Possibilities are: It's a compulsion, vocal tic or stereotypy, that probably increases when you're anxious. Usually it can be treated with Clonidine or long-acting guanfacine, but it sometimes requires neuroleptics. If your cognitive ability is in the "average" range or above & your receptive & expressive language abilities are also good, cognitive-behavioral therapy or specific habit-reversal therapy may help.

Maybe: Some drugs might help with impulse control, but they can come with unwanted side effects. If you can already recognize these urges a good behavioral therapist might help you better learn to control them without drugs.

Tics: You have a good amount of insight into your condition! It is not unusual for kids and adults with HF Autism to make unusual sounds, and have repetitive movements. Whether to treat depends on the amount that these behaviors and urges are affecting you socially. See a good cognitive behavior therapist for starters and see if you can work towards suppressing the behaviors. Meds may follow.

Tics: You may have vocal tics. Tics can be treated with medications such as knifing or guanefacine.
