I was perscribed ultracet for kidney stone surgery. Im was 20 yrs old. Im now 21 and am addicted to the drug. I take 4 a day and if i miss a does i go through withdraw symptoms that include headaches but mostly im unable to sleep. i cringe at night, my legs and my hands i constantly jerk them up and squeeze into a ball. My husband says i keep him awake. This drug gives you a great feeling, and it does take away the pain. When im on it all the time, i sleep 12-20 hrs a day. My life depends on this drug. I have no problem at all getting a perscription, and my insurance covers all but $6.00. Im a real drag when im off it. Please think twice,three times before starting this drug. The cons outweigh the pros.
