Yeah you still roll... But it sucks shitty ballz... Im a heroin addict for 6 years now and i went to a Massive 1 time while i was sick and i will never ever even think about going to a rave or anywhere else for that matter sick and rolling. You still kinda roll but then your thinking speeds up and you start feining even more and i started getting really really bad kicks to where i couldnt sit down and be calm for longer then 30 seconds but my legs were cramped up really bad so i couldnt walk for any longer then a minute or so. I couldnt enjoy light shows, couldnt dance, couldnt hit on girls haha.... all in all it just sucked really bad. DONT DO IT. well i guess it kinda depends on what you use and how bad you are. some poeples withdrawals arent so bad (mostly mental) as where I start puking my brains out after 24 hours without a dose of h.
