[Heaven's Night]

I can't explain light headedness and loss of energy, but to me this sounds like your body just reacts really strongly to elevated estrogens or progesterone. BO is known to contain bioidendital hormones to some extent, exactly what extent isn't known as they're not harvested at the same time of cycle and not tested for hormone content before being freeze dried and ground to powder.

Everything else is something you might get from starting conventional HRT, but the timings you speak of sound strange, like there's a really fast peak and it soon lowers. To me this is really like first reactions to feminising hormone treatment.
