Brooke Mueller, who's currently in rehab, is telling friends she doesn't want to end up like late singer Amy Winehouse, Breaking Celebrity News has exclusively learned.

As we've previously reported, Charlie Sheen's ex-wife entered an undisclosed treatment facility in the U.S. last week after having another relapse.

At first, Brooke had planned on going to Mexico to be treated at a clinic in Cancun that would have given her ibogaine, a controversial drug that is illegal in the United States, that is supposed to stop cravings for drugs. Ibogaine has very dangerous side effects, and can alter a person's personality dramatically after taking it. Brooke realized that taking the ibogaine would do more harm than good, and ultimately, needs to do very hard work to become and stay sober.
