Our opinions differ here. Personally I think it is dangerous to let someone else dose your drugs for you. I have to assume most people here are intelligent enough to own and know how to use a milligram scale.
Never let someone else decide what drug and amount you put into your body. Always do your own research and dose the drugs yourself. I trust RC vendors as much as I trust the local thugs dealing heroin on the corner.
Good luck with quitting, you may well need it. I detoxed last year after a 8 month 60g AM2201 run (hitting 300mg+/day towards the end) and it was hell, takes a week to feel something approaching ok, a month to feel 'normal' (as far as I could remember it). General anxiety, derealisation, dodgy stomach and cravings still persist 2 years later, although I have been indulging in a gram binge of a synthetic once a month or two. That's stopping now as I've realised I was inducing seizures without realising.
Things you may need to help withdraw if you're in the same state I was:
Blender or milkshakes cause solid food will be hard/impossible to keep down or eat enough to actually stay healthy/not loose weight.
Something to keep blood pressure in check, it can get dangerously high when withdrawing, I was prescribed proponanol 10mg, can't remember what my blood pressure was at the time but it was high enough that I could see my pulse on my temple in the mirror.
Diarrhoea relief medicine.
Lots of clean sheets as they'll be soaked in sweat every night.
Anti-acids to settle your stomach enough to eat or just keep down water.
Again good luck, I really don't envy you.
