Hi Orchidlady - wish I'd seen this thread earlier, when I'm not hanging around on MN with all my woes, I'm a MH nurse in real life!
Sorry you're going through this, it's so tough on loved ones, you feel powerless, helpless, burdened, overwhelmed, resentful and out of your depth I bet.
Diazipam is a tranquilliser. It's often prescribed on short courses at the start of other meds, and calms the patient down, because ADs take a while to kick in, often about two weeks, and ADs can heighten anxiety and suicidal tendancies in that time. So a course of Diazipam will be prescribed short term to counteract the initial effects of the ADs, and will numb the patient to some extent, whilst the ADs start to work. Once the ADs work, the Diazipam if only a short course is stopped immediately, or if a long course, then it is gradually reduced. Diazipam is highly addictive, which is why its usually prescribed in short doses.
Glad you called 999, you had no option, mixing booze and 'pam isn't good - both are depressants.
How is he today? Has he been admitted? Hopefully this will make the MHT step up and do more for him.
You have my sympathy: you can only do so much, the professionals will have to take over, you need a break from this - even just half an hour now and then, go for a walk, have a nice bath. You're not responsible for his wellbeing. Take care.
