For what it's worth, I've found 3-mmc to be not really suited for functionality. It can be done , if you stick to low to medium oral doses (say no more than 200 mg in one go), or have no more than two lines, but it's a hell of a struggle, and there's always an itching irrational desire to do just one more line if you go down the intranasal admin route. In fact if you want to keep even remotely functional - just forget about railing it! Chances are whatever you'll get through whatever stash you've got as you say (despite any good intentions). Other people s experiences might differ, but I find 3-mmc much more suited for recreational than functional use. I once managed to do a 45 minute phone conversation after a couple of lines, but it was a struggle not to ramble , or go off at a tangent, and to keep it focussed at times. For a more functional and focused experience, I'd recommend 2-fma.
