My husband was a serious alcoholic who was diagnosed as bipolar, anxiety disorder, sleep disorder, ADHD and on and on... for over 10 years he was prescribed vast amounts of prescription medications to "treat" sad disorders including benzodiazepines.
Attempts to titrate off the meds was impossible for him outside of residential treatment...
shared all that to say that the doctors involved said it would be at least 6 months (his "manic" episodes were usually about 3 months apart) before they could begin to determine where the alcoholism and its symptoms began and potential bipolar/mental illness began.
We are going on 9 months alcohol and illegal/prescription medication free and he has not had a manic episode or any bipolar behavior. He has had his days of PAWS that we both were able to deal with and that passed quickly.
The rich and famous with addiction issues gravitate to doctors that will liberally dispense the "pill for every ill" and it is my educated guess that Sheen is dealing with life and attempts to detox off alcohol and illegal drugs with scripts that are going to derail and sabotage that effort.
Benzo's are deadly mixed with alcohol ... but the effect for the alcoholic is pure utopian bliss for them in their drugged out world while in reality they are blacked out and acting in completely bizarre and even an insane manner.
It is frightening to watch someone self destructing in a world of delusion... for us we see it all the time but the public at large has been getting an idea of how difficult it is for those who are trying to help loved ones through watching the celebrities and their families try to cope with severe addiction.
