As far as "experience expectation" goes I can say this: expect to experience a mind altering haze where for each and every single moment you will spend calculating ways to get more. I started with a 10 mg hydro like most people and got to snorting at the very least 60mg of oxys a day. The high I got was amazing. I felt warm and happy and fuzzy, and I wish more than anything for one to magically appear in my hands right at this very moment. I actually dropped half of one over 5 months ago in my bathroom and I still to this time find myself desperately searching for it-removing the floorboards and everything. I don't want to sound like a cream puff, but just say no! The high is amazing. But it's truly not worth all the stress and agony that it could-and most like does- lead to.
