This happened at the weekend, and again today.
Just whilst doing "normal" stuff, around the house (ie. not stressed, or in difficult situation or under pressure) I become aware that I seem to have what I can only describe as "the jitters". Hard to describe, but it's a slightly surreal feeling, like I am in a bubble and I am quite shaky.
Not been drinking, not had excessive coffee, not overexercised - calm and normal day both times. Have eaten and drunk water as normal.
It took quite a while to pass at the weekend (at least a couple of hours) and it has just started again today.
Just no idea what it is. Doesn't stop me in my tracks, but is distracting and my mind is quite fuzzy.
Any ideas? TIA
