Tried this substance around 7 times now, mainly experimented with smaller dosage ranges (15mg) for social settings, watched the new blade runner at the cinema with this and had a great controllable experience.
One negative effect I haven't seen posted by anyone is a post trip body load with it that I get.
On my second trip I decided to take 20mg and then redose 20mg x2 over a couple hours being unhappy with the effects, only until after did I understand why people said redosing was pretty much pointless and have to agree didn't benefit from it and haven't done it since.
However after first dosing +5 hours I got this very strange, quite scary body load. Which I remember being a burning itch sensation all in my body and remember my skin feeling hot and tight, it wasn't painful enough to visit a hospital however it was as though someone was prickling me with hot needles all over my body, this subsided after about 4 hours of tossing and turning in bed which is when the faintness, nausea and vertigo kicked in ended up being ill for the rest of the day being sick.
Quite scary and a good kick up the arse to not do something so stupid and 'chase' the high.
Luckily I have always been responsible with my doses and settings so recognized this fault to put me back in line probably needed the experience to remind me of that. That being said on any dose of metocin 10mg+ I notice this bodyload every so slightly on the latter stages of the trip and up to 6ish hours after, feeling a pricklish heat to the skin perhaps a slight swollen feeling.
Would be interesting if anyone else relates to this, or whether it is an allergy thing despite doing allergy tests.
Other key information was I attended a rave 5 days prior where I took lsd, E, metocin with hourly intervals( 40ug, 100mg, 100mg, 10mg) so this probably attributed to the severity of the bad bodyload. However I still experience this burning, itching sensation on a much milder scale, enough so that I can sleep after a smoke on the smaller doses but there is definitely some unatural skin feeling on any dose above 10mg.
