SWIM's still working toward being able to write a guide, but he'd like to add a quick note.
SWIM found that 35mg of THH missed the mark for 50mg spice, but his friend accidentally got a bit more THH (likely between 40-50mg) and had much more activity than SWIM. The next day, SWIM had aprx. 70-80mg of of about 1:1.5 harmine to THH, and it was incredibly strong. SWIM got the end of the short playlist he was listening to and decided to play around with audio hallucination (sort of the audio equivalent of CEV, since it's not indistinguishable from real sound...more like a voice in the head that you can "hear" quite clearly). Anyway, SWIM felt incredibly heavy and debilitated, the room was largely unrecognizable, and SWIM reached a sort of infantile state (happened with harmaline in prior experimentation, but in a different sort of way).
SWIM would guess that to adequately activate spice in sublingual use, one would have to take nearly as much of a harmaloid as spice, if not more--at least in the case of THH. SWIM wouldn't go much higher than 80mg of harmaloids and would keep it in the lower range with higher ratios of stronger RIMA's, like harmine and harmaline. Don't skimp too much on the harmaloids, or the few harmaloids and the bit of spice administered will be wasted.
SWIM recommends 30-40mg spice between 1:1-1:2 ratio with harmaloids, going easy on the harmaline and harmine.
Also, deep breathing seems to help keep SWIM's mouth drier during administration.
