Not me, keeping it in my mouth without swallowing produces a light local anaesthetic effect.
Funny you say that, i've found at certain points using ethylphenidate tonight - very sporadically - that my front teeth and the surrounding gum area feel slightly numb.
---------------------------
I also felt i should log on to bl and just take the time to say that this substance is a really nice one. For me, when i choose a drug, i choose one that most adequately suits the circumstances that i will/or may find myself in.
Tonight, i've gone to the pub - had a few beers with a couple of mates and sniffed a very modest amount of this stuff over the night... Intended to act as a nice background buzz to match the beers and the football, this substance has proved unlike any other i've tried before.
With cocaine / mephedrone et al, i find there's always a very persuading, ''leading astray'', euphoric kind of feeling battling it's way out of you, pushing you to put your headphones on / go home and masturbate/ go for a midnight walk etc. And this ultimately makes you slightly less sociable and less concentrated with the night at hand and the people your with.
Ethylphenidate has not been overly stimulating (ie. no jitters), unsociable (ie. composed in conversation), overly euphoric, nor even a pain in the arse - it has simply carried out its duties tonight wonderfully.
Adding a nice layer of satisfaction to a casual night of drinking, without getting in the way.
Because of this unique situational prowess - i will be using this again; Just as i would use high quality charlie at a house party, mdma at a good rave, or methoexetamine in my bedroom watching a documentary.
