are you sure you were 'tripping' for 2 days and you werent just out of it, cause its normal to feel out of it and generaly weird for a few hours to a day after you trip, and since it was your first time tripping on anything you might not have been able to distinguish when the trip ended.

but you could be one of those caucasians so id be careful about doses, if you tripped real hard off 700mg id say go to a 1000mg and see how that is then go for higher doses another day if you can handle that amount.
