Actually, even I rather enjoyed meph/M1 as a combo now and then, MM. Much preferred it to straight meph anyway.
And whilst in confessional mood, there was one meph combo I genuinely adored with no reservation. Was the very first time I sampled either drug and - drugpiggy that I can be sometimes - decided I may as well combo 'em up 8)
Combo of joy for me was 2C-I + meph. How bizarre is that?!? I find both somewhat stimulating in "the wrong way" (for my taste anyway) but together they seemed to cancel out each others' rough edges and was mellow as fuck. Insanely euphoric with just the right level of swirls for a fairly light 'n' fluffy sunny afternoon trip. Was lush so it was. Don't recall the doses cos was years ago now (12-18m before meph hit the UK properly) but all dosing was oral from memory. Think I got through the whole gramme of meph over the course of the day but don't recall finding it especially fiendy.
Would be interested if you knew roughly the amount of 2c-i. I reckon that might be quite an interesting experiment. Too much meph would flatten it though wouldn't it. I've never tried this, but I've often thought that if you were having a bad experience on psychedelics of any type then meph might overide it.
