A flood of serotonin, has desynthesized your receptors and to normalize this..
The brain is compensating by allowing you the use of only four of your given senses, at any
given time, with the missing one constantly switching.
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.
