Pain
"I was prescribed this medicine for moderate pain after surgery. My incisions bothered me, and I took 4 pills a day for the first 3 days, then usually 2 a day. However, the side effects: nausea, palpitations, dizziness, drowsiness AND sleeplessness, constipation and mental vagueness were really too unpleasant to be rid of minor pain, so after a week I stopped taking it. It is annoying that after stopping it, I suffered nausea, palpitations, and weakness/drowsiness after large meals--possibly due to withdrawal."
