Health - planning a vacation--using multiple substance

[samsa]

swim is planning a five day vacation to san francisco where he and a friend will be enjoying the sights and sounds of the city whilst on a binge. swim is generally a safe and responsible drug user and realizes he is sort of throwing caution into the wind here with the idea of an intentional binge, but he still intends to be as safe as possible. The following is a list of substances swim will have access to during the 5 day trip. He wants to know what would be the safest way to space these substances out in an order that is responsible while still being able to use all or most of them.

Tramadol
Cyclobenziprine
LSD
LSA
MDMA
methamphetamine
Nitrous oxide
Ether
Diphenhydramine
hard alcohol. rum n vodka.
viagra

swim would generally take the tramadol/cyclobenziprine/diphenhydramine together to increased potency and not individualy.
he is also concerned about seizures (although he has no history of them) or other side effects when combining tramadol with other substances.

he has never tried ether (diethyl methinks) and is cautios as to its effects.

he would like to space out MDMA and meth as much as possible to avoid seratonin complications.

he is also concerned about the respitory depression LSA provides and may just skip this item.

your advice is appriciated.
