Is the insomnia of a similar level compared to the originals? I liked the original Spirits because if you snorted 2 or 3 over ten minutes you could get a decent rush, a friend compared it to iv ice which while I agree the 1 or 2 if your lucky hours of euphoria doesn't really compare to the 5 to 6 you get off good ice. But if the new range doesn't really have the rush its not going to be worth the lack of sleep.
The last time I did the SC2's I wasn't able to sleep till over 30 hours after the last line

I understand that stimulants are going to make sleeping difficult but these take it to the extreme, its easier to sleep after ice than these - I was just hoping the new range would be better.
