Cheers for the responses, people.
Having read around a little bit more I was a bit wary of taking the mephedrone as not a lot seems to be known about it. I hit the pub after work, had 4 pints of Stella, some food, went back to mine, drank more lager, listened to some music, went to the pub, had a can of Red Stripe, dropped 1.5 pills my mate had brought down from Manchester around midnight (white hearts which turned out to be reasonably good, not stupidly strong but clean and quite a nice dose of MD) and drank a few more bottles of beer at the club. Danced for a couple of hours and shot the shit with people till around 3 o'clock, at which point my pill high was waning so me and a mate decided to have 1 *of a proprietary branded capsule* each.
Now, as I've explained, by this point I had drank a fair bit of booze and had 1.5 pills so I'm not sure to what extent that contributed to the effects or may have clouded my judgment but I have to say that *the proprietary branded capsule* seemed very good: nice come up, euphoric high, blurred vision, talking nonsense for about 15 minutes whilst coming up strong, gurning away like a fool and stayed feeling nice till about 6 in the morning when i went to bed. In short, it reminded me of what it used to be like taking a nice pill when I first started. It was certainly a much stronger high than the pills we'd had, so I'd reccomend it if you can't find good doobs but still would prefer a pill experience to crystal. Only downsides were the price and the fact that I found it much harder to sleep than off street pills. The comedown really wasn't too harsh although, it's hard to tell as I'd had normal pills too plus a fair bit to drink so couldn't necessarily judge what was what.
