It common for me. As to what to do about it. Well no, tools and skills for dealing with mania can appear much different than depression. Mania is not a good time for me, hypomania sure. Mania is an awful experience for me, sounds off but it's true, and I believe that is common with full blown mania.

One of the best things is to prevent mania in the first place. Since we know it can be hard to manage once it's in full effect. So manage your sleep, diet, routine, light exposure, stress ect. I have found a lot of help in yoga, meditation and mindfulness, seems to helped keep me away from becoming manic just as much as depression. Who knew?

Same thing applies to while you are actively manic. Regulate your life in a way that supports what you are trying to achieve, and that is balance. I know, sounds so flippant of me. When you are manic you can do these things. It might hard, you might screw up, you are defiantly not gonna get it perfect, but is does help.
