Not sure what I've taken....

I am not sure what the heck I've ingested lately but I'm like a whirling dervish today. I just haven't been able to stop. Walking into town and back again. Shopping for food (which I normally hate doing). Got home and started unpacking my suitcases and tidying. I then got out the cleaning bits and started cleaning the kitchen, bathroom and bedroom/lounge. I'm now baking some banana muffins.

I wonder if it's going to have some kind of backlash/come down?
