I would have to agree with all the above advice.
Its your first time, do it somewhere safe and comfortable.
I am experienced with acid, and it is my drug of choice, but still, whenever I am trying something new, I always try it at home in the company of friends first. Basically because you never really know what your in for, every trip can be different from the last.
Acid is very diff from MDMA, and depending on how much you have and at what strength it really can dump you on your arse.
Taking MDMA with acid for the first time is also not a good idea IMHO, when your experienceing a new chem I think its important to really feel what it is doing to you, and this isnt possible when your are loading with other chems at the same time.
Raves can also be very daunting and overwhelming when on acid I have found.
Your friends had a great time when they candy flipped, but acid is also very personal, and you can never use the rule "they liked it, it worked well for them, so I should be fine"
Either way, I hope you have a fantastic and memorable NYE whatever you decide to do!
