I can understand your anger. Everything in life has benefits and risks, and unfortunately DI is a possible side effect from any of the drugs in that class. For what it's worth, I've seen people who have not had good luck with their depression on other medications or on their own with therapy get their life back with Abilify. For the right patient it truly can be a miracle drug.
I am VERY against what are known as "Direct to consumer" drug ads, as frequently patients will ask for things that are either much more expensive than an older drug that works just as well but isn't advertised, or ask for drugs that have nothing to do with their health problems, simply because the commercial is interesting and says "ask your doctor if Jamitol is right for YOU!". I spend probably half an hour to an hour a day explaining to people why the drug they saw on TV ISN'T right for them.
To be fair, also, MOST doctors won't write a drug just because it's new. Most of us want to see some compelling data as to WHY the new latest drug is going to be better than what we know and have been using for years. Even the doctors that want to try the latest aren't doing it "to give us meds that are going to mess us up worse than we already are".
While its frustrating for your psychiatrist to send you back to someone else for the problem they created, I've found that psychiatrists really aren't the best for dealing with DI. Generally a good family doctor, a kidney expert (nephrologist), or a diabetes expert (endocrinologist) is your best bet.
Things you can do for yourself without a doctor would be to start checking your blood sugars on your own. You can get a glucometer at the drug store without a prescription. Having some knowledge as to what is going on with your blood sugar will at least allow you to try to control some of this with diet and fluids.
Glad that you're back, Soumise, and sorry you're having troubles.
Regards,
Doc
