I never used to have malaise, I grumble, but then I remember I had muscle-knot migraines instead. Not sure which is preferable. Malaise has no boundaries or definition so you never know when it will end; migraines have a definite progression and symptoms but are much more debilitating. The malaise might go away if I turn on the AC (we are such wimps here: it's only 25C) or it might be caused by cool air blowing over me at night (from window fans, meaning muggy dirty air.) It might be allergies; it might be a subluxed vertebra; it might be the humidity; it might be all of the above.
But whatever, is the weekend and I can be as malaisey as I want until Wednesday.
Shall note that I have three months worth of one-a-day lenses, which are unconscionable in terms of packaging but oh! so kind to dry summer eyes.
