I think it's just the joy of feeling normal and being able to do the things we want to do. We just overdo it.
Ditto to above comments.
I don't feel like I HAVE adrenalin anymore, tho. I just get frantically busy running around and sometimes sit back watching myself, thinking "What a loon." So when the mania strikes, I try to dial it back, because I do pay for it the next day.
It is nice to know however that I CAN still operate in overdrive, which used to be my normal cruising speed. Sigh!
do you think this could be 'adrenalin' related - ie; when adrenalin is circulating it 'over-takes' pain sensation etc,
Yes. I relate. On good days I just keep going and going. Then I pay for it the next day.
I can relate to this. Sometimes I feel that my body is so used to fighting the fatigue/exhaustion that when those symptoms let up, I feel unusually energetic/borderline manic.
Like if you are playing "tug of war" and the other team suddenly releases the rope, you go shooting back because you were still expecting the resistance.
Also, I think we feel so behind on life, it's hard not to want to make up for lost time. Of course, it's easy to over-do it and then set yourself back, but who can blame us for trying?
