Doctor changed my pain meds from 40 milligram oc twice a day, to 120 milligrams of avinza once a day. Took my dose at 2 pm today, was in withdrawl in about 30 minutes. Now I feel like hell with panic attack symtoms, and mild withdrawl! Would it be safe to take half of one of my 40 milligram oxycontin?
avinza overdose?
