The plateaus depend on your weight. So someone who is bigger will need a higher dose.
Here is a link to a
DXM calculator: ***edit*** guess I can't post links : / ***
Just google DXM calculator
The first 2 plats are very euphoric. But in order to get the most
euphoria, a single dose must be taken instead of a few doses. This is because DXM is converted to DXO. DXO is what gives the euphoric feeling. Any later re doses will not be converted as much, and will result in more of a mind fuck. The hangover/"afterglow will be more intense and will take a body toll.
The higher plats are not euphoric. Music euphoria will still be very present however. The higher plats are best saved for a shamanic experiences. Also, a trip sitter is recommended for the first few times in the higher plats. It is very hard to walk (robo walk), dehydration is a factor( as any plat), and figuring out a door knob could take an hour (no joke). This is why a trip to the bathroom is hard.
You are correct when you said to only use DXM products. DXM poli is a time released prep. The high is less intense than DXM HBr if you took the same amount and compared. The DXM poli will last up to 12 hours, so just make sure you start smaller doses.
I find that if you have
weed, a lower plat trip is ideal, as the weed/
N2O will really kick it into gear.
Let me know if you have any other questions at all. : )
