I don't know if this helps but I had to have chemical induced menopause in my twenties and again in my thirties for another condition. Had all the classic symptoms and my bipolar meds only had to be adjusted slightly. I did have very slight swings and did have trouble with sleep but was told even without bipolar, this was not unusual for menopause because it varies.

Another friend who has BP just went through menopause and had to have her meds adjusted during it but was not significant and had no trouble with sleep; another with BP had menopause symptoms but no trouble with her BP. It just varies from person to person. Just be prepared and know that it might be an issue so to have help in place should it become a factor.
