Don’t remember how long you were on 1 mg but reducing from 1 to .5 is very dangerous. These drugs need to be reduced very slowly. The songs you are hearing are probably from withdrawal. You are playing a dangerous game as you can have a seizure if you don’t come off slowly.
They do sell a .25 disintegrating tablet but not regular. I broke my .5 pills in half and only ever took .25 at one time. You were taking three times as much. Please be very careful.
