Overdose
A flood of seretonin, has desynthesized your receptors
and to normalize this the brain is compensating by
allowing you the using of four of your given senses at
any given time, within the (...) switch, so if you can
see, smell, taste and hear you can't feel anything.
You did exceed the dosage.
A drug just has to pass through your system. Trust me,
you'll know when it's gone.
