Rapid cycling sucks. It's so draining to go from high to low and back in a short time. BTW, DSM considers rapid cycling as 4 cycles in a years. Mine were a day.

Meds can play a part at both ends. My rapid cycles were caused by a med reaction. I’m had just changed meds and reversing the change made everything well again.

There is the is the other end. If not coming of a recent med change, a med change could help. There are a number of meds that might be able to help with rapid cycling.

No matter what, check with you psychiatrist or doctor for further help.
