Medicines are both a blessing and a curse. My sister has Tourette’s, and when she first started taking the meds she was a Zombie for 2 years. The meds completely erased her personality, which had been vivacious, funny, outgoing. But she stuck it out because the alternative was unthinkable, and finally she adjusted to that strong medication. Her personality returned but the medicine worked to suppress her symptoms. The best of both worlds.
