Bipolar IIIt is a melancholy of mine own, compounded of many simples, extracted from many objects, and indeed the sundry contemplation of my travels, in which my often rumination wraps me in a most humorous sadness. -- William Shakespeare
Yep, serafena is right. Finding the correct balance of meds can take some time. I know it is difficult, but it is something that we have to go through because there isn't just one formula that works well for everyone.
Be patient and take one day at a time. Maybe you could keep a log of how you feel each day and try to find out what some of your triggers are too. It will also help you to remember exactly how the meds are making you feel so that you can remember to relay everything to your doctor. In the meantime try to find things that you like to do to get away from those times that you feel you are becoming more irritable. It takes practice. Continue to keep your doc informed.
Wishing you wellness.
