He said he did not know how he contracted the disease.“I was doing a lot of drugs,” he said. “I was drinking way too much. I was making a lot of bad decisions.” Sheen said on “Today” that he now had a responsibility to better himself, and that he hoped that his decision to come forward would help other people. “Hopefully, with what we are doing today, others may come forward and say, 'Thanks, Charlie, for kicking the door open.'”Sheen said that since his diagnosis, he has never missed taking his medication.
