^ I'd say lack of morphine is probably for the best in this case. Have taken codeine with it a coupla times now and it has the same effect as it does on G -
massive potentiation of both. And - sadly - not the good kinda potentiation. Is all overly-spinnyheadednesses and spazzfests.
Can see how folk might get a taste for this stuff. Is not a terrible alternative to GHB/GBL... sort of. It has most of the same effects but the negative effects are definitely more pronounced with frequent use. Getting the dose right has been a bit of a chore. Mucho time over the last few days spent either spazzed out or unconscious - and for much longer periods than GBL due to the lengthy duration. However, when you get it right it's really rather nice. And cheap. And easily available. I'd still rather have guice though
Differences noted include appetite - nothing like as bad for the ubermunchiez you get with GBL but definitely a whiff of the muchiez. Also the G-Horn is very much in effect but much harder to do owt about. Partly cos I've not quite found my sweet spot yet and keep overdoing - or underdoing - it and partly cos it's more or less impossible to reach a satisfying conclusion (although if you manage it the conclusion is not just satisfying it's fukkin
outrageous 
). I suspect this may be largely down to lack of anybody to spread the joy to though.
Definite negatives seem to be rapidly rising tolerance and rapid onset of physical iffinesseses. After just a handful of daze of daily use I felt like I'd been hammering guice 24/7 for weeks. This may be due to hammering guice 24/7 for weeks on several previous occasions, mind. Mainly noticed pretty extreme exhaustion due to residual and rebound stimulation (and, of course, my total lack of willpower and moderation 8)) and some kidney discomfort. Probably due to dehydration cos it makes you piss like a racehorse. Have also had the chronic shits for a few days which may or not be related.
Fortunately/unfortunately I bought a larger amount the second time (100g) so have plenty to use and abuse but also plenty to taper down slowly. Which I think is gonna be essential.
