Well you can always see a new Pdoc and get a second or third opinion..

Bipolar and Borderline share alot of the same symptoms/reactions. lots of people can skip doses of meds and still be okay for a bit, factoring in Half life of meds..

Chasing Hypo/mania is a tricky thing... in the majority of cases people have a full blown episode , often wind up IP and once the dust starts to settle there is a path of destruction that you need to clean up and lots of amends to be made. Some people wind up in trouble with the law..

If your feeling to flat the best thing to do is let your Pdoc know, Often Medications needs to be tweaked or outright changed. Winter is a terrible time for most people with Bipolar for depression.

Think carefully before you act. Stay safe
