Hugs
My brother (who I am very close with, he is a widower and I help him with raising his 3 children ages 10, 15 and 16) has been dealing with Bipolar since he was 20 years old. In addition my father is bi polar and my grandfather was. I don't believe my grandfather was ever complaint with treatment (he died 30 years ago) but he also was an extremely rich factory owner so he "got away" with things by being eccentric and powerful.
My brother and father are very complaint (coperative) with treatment though (as is my best friend who is also Dx with Bi polar.) Women present differently then men, in fact there are many different categories for the illness. In addition substance use plays a major role in functioning (or dysfunction as the case may be.) How complaint a person is with treatment and medication can really make a difference in the dealing with this condition. The good news is, it is treatable, med and therapy really can make a big difference. Some things will change with treatment, some won't (some are personality.)
I often think this illness can be as hard or harder on the loved ones to deal with then the patient. I know it is for my mother. However she always see my father as the identified patient and it is all about him. I really wish she would accept that there is some things about him that isn't going to change and get some professional help in dealing with this herself. My father is often very depressed and does nothing (leaving her to cope with life as close to a widow) or is "high" and is pretty happy, but gives away money and almost everything else, spends it like crazy and is pretty fun to be around for everyone else, expect her. We all like it a bit when dad is "high" he is alive again. For my mom it is like he is out of control and she never knows what will happen.
I am also a clinical social worker (but a SHAM for the past 2 years.) I used to work in an outpatient mental health clinic.
Pay attention to your Dh's sleep patterns. When they are off that is a big sign that something is happening and is always good to tell the Dr. Try to find a Dr. that is willing to work with you too, after all this really effects you and your family. Oh and pay attentive to weight gain and side effects. Lithium is effective (more in men then women) but tremors and weight gain can be bad. There are many other options, but Lithium is 1st course treatment and many of the others have the same side effects. Still side effects can be hard to live with, but not as hard as living with out the treatment.
Zyprexa, and Klonopin will make him pretty tried (that is standard meds for hospitalization.) With time the Zyprexa shouldn't make him as tried, but will help control mania. Klonipin tends to make people pretty sleepy no mater what, so many people take it only at night. You are also going to find that these meds are giving in different doses to different people for different reasons. For example people will say "My cousin was on Zxprea and he was hearing voices......My sister was on Klonipin for as sleep disorder etc" Don't let that bother you at all. It is pretty normal for doses of meds to be tweaked and changed too. It might even take some time to find the right combo. It can be trail and error to find the right meds though.
As hard as it is for everyone to get this Dx, this is a good thing. Much better then living with the symptoms, and not treatment and help. You and him are on the right path for things to improve now. Hugs again.
