If quick is: the day before yesterday I was doing just fine then yesterday morning I listened to some Youtube videos including Stairway to Heaven (). I think I was hypo yesterday. The same few bars of the climatic up tempo of the song played in my head all day long and I couldn't get those bars to stop as I tried to get to sleep last night. While that repetitive music played in the background in my head all day long, I was plotting complete books in my head all day long and did a little writing. I was still writing possible posts on PC and books in my head as I was trying to get to sleep. I was tempted to get up and write. What stopped me was that I teach classes for VIPKID (a remote job for a Chinese company where you teach students English) and I have to get up for that job everyday (7 days a week). If I had gotten up and started writing or posting at PC--my teaching would be cr@p today. Also, thanks to PC, I realized that I was hypo and that getting up (rather than just resting even though laying there wanting to write some of what was going on in my head was what I might have done in the past) would only make it worse. Tried to lay there and meditate but it was useless (sometimes I can)--just couldn't quiet the voices. Eventually, I did fall asleep. I am not feeling hypo now. Some of the books I wrote in my head do not feel as brilliant now! So if "switching" in 24 hours would be considered flicking to hypo quickly--then I do. I am glad that I have gotten better at recognizing when I need to reel myself in. Also, I now recognize how important it is to stick to a schedule. Reading posts on PC and learning to be more self reflective has really helped me.
