opiate dependence
"This medication gave me headaches from the very first dose. They lasted 3 weeks. I volunteered to try bunivail, so I stuck it out for 3 full months. I have to admit these have been the worst three months ever. I would sweat all day. Hot yet had the chills, I couldn't enjoy food. I forced myself to eat. I would start having withdrawals 4-5 hours after I took it. The ungodly hunk of slim that was left over after an hour would float all over my mouth. This drug sucks. Today I got put back on subs and I kid you not  I feel amazing. I am normal again, if I missed a dose of two of subs I was fine with this bunivail I had to do more than I was supposed to just to feel normal. I wouldn't recommend anyone to switch to this crap.."
