Hamster: Racing thoughts can still exist in depression. It can exist in a person undergoing stress and without a mental illness. It is also very common in anxiety which tends to follow depression. None of these symptoms are black and white and racing thoughts do not necessarily mean mania.

Scared: The personality change happened before the meds during the depression which is why I am saying you can't automatically attribute the unappealing attitude to medication. It is a messy situation where you don't know what is the disorder and what's the medication and you simply can't pretend that you know which one it is.

Also, the alcohol use is self medicating. Some people have very positive responses to being drunk on medication. People not on medication and those without MI will have very positive results from being drunk .... that's why we drink. This does not mean your husband has been returned to his self, it just means he is drunk.

All I saying is don't jump on the assumptions that it's the meds or mania, all the symptoms could be the original underlying condition. It's obvious that your husband is being ineffectively treated, but part of effective treatment is to not reject treatment options or pursue inappropriate ones because you too quickly set your mind on one interpretation of the events.
