I have been prescribed Butrans patch at 5mg dosage i put it on at lunchtime yesterday and have got up this morning to feeling a little drunk!!!! a little light headed but my pain has improved better than its been in months !!! does anyone know if the feeling will wear off as my body gets used to the drug or am i expected to feel like ive been out and drunk 25 glasses of Baileys!!!!!! as long as i leave it on!!!!
