Meprozine and wisdom tooth

i was prescribed meprozine after having a wisdom tooth pulled the day before yesterday ,and hardly can remember any thing afterwards just a hellish blur.it did little to kill the pain but was very succesful at making me too dizzy to walk. i was too disoriented and confused to carry on a conversation with any one and whenever i went into the next room i forgot why i was there. it was all quite embaressing . i took one somwhere between 6 and 7 this morning but didnt take any more .its now 3:15 pm. i'v ben suffering accute feelings of paranioa, insecurity depression rejection and aggravation ,with some hallutionations for the last three days. my coordination is still bad. i had some trouble typing this . i'm angry that they can sell this crap as "pain killer".
