I'm not a fan of the cathinones either. Methylone does virtually nothing for me, empathogen wise and MDPV causes so much uncomfortable sympathomimetic PNS activity and wicked headaches, even at a 5mg dose. For some reason, my MDPV experience was even worse than methylphenidate in terms of PNS stimulation (i.e. massive sweating, bump in heart rate, jitteriness, headache, flushing). It was like drinking 8 shots of espresso while chewing nicotine gum at the same time. Not only was it not ideal in terms of ADD therapeutic effect, it was just not worth it period.
