Side effects - Prevent Falling Asleep?

[Salvinorin A]

It happened again. At night 11pm, dosing 2 bottles of Zicam Cough Mist Max (769mg), lying on a towel with pillows as a back prop.

The first time, SWIM was enjoying the CEVs and then wakes up and it's morning. The second time, the exact same thing happens except SWIM was well aware of the possibility of falling asleep.

SWIM only likes night trips (day trips are just too bright), and he usually does it alone. SWIM used to take the syrup and didn't fall asleep (came on much slower, and more painfully nausea-wise). However, the Zicam hits like a ton of bricks, and SWIM enjoys the CEVs and the even more promininent OEVs!!! (tried with GF juice, works every time).

So SWIM got sick of OEVs, closed his eyes and just thought to himself (this is after accidentally opening his eyes during an OOB) "SWIM is still on the climb, there's gonna be a whole trip lying ahead of SWIM"

And then he wakes up again. SWIM particularly hates falling asleep, because it is a waste of time, and SWIM doesn't like taking DXM, he feels like he is ruining his brain and he feels shaky for a few days, so usually he feels better when he doesn't have to take such high doses so often.

As for solutions, any suggestions? SWIM is thinking of having a sitter to wake him up if he falls asleep (will that even work?), or maybe there is a way to just stay awake, like sitting in a chair uncomfortably. Caffiene can certainly keep SWIM awake, but with DXM? could affect the trip.

Any help would be GREAT. Thanks guys!
