I've found that pharmacists are often better than doctors at catching drug interactions. Polypharmacy is the prescribing of 5 or more drugs. Many seniors take that many. I certainly do. Make sure you always use the same pharmacy so they have a complete record of all of your medications.
Also, I thought antidepressants were not recommended for normal grieving, though talk therapy could be useful.
Believe me, I am not against healthy foods and vitamin supplements. I keep hearing about apple cider vinegar and am interested. I just realize that it's not enough in my case. Even adding talk therapy, which I've done in the past, is not enough. Bipolar disorder is a physical disease of the brain and it requires serious medication.
I'm just glad I was born when I was when we do have treatments. Even 50 years ago, people suffered and they often died.
