Sperwer, Respect! First- your appearance changed so much from that pp contest that I almost did not recognise you, recomposition in a year is unbeleivable. Training wise- also lot of improvement.
And lastly, well- you know.... Adrenals- your adrenals are bit exausted I think, which results in mineral/water wasting/dehydration and also your body trying to compensate by pumping adrenaline in- which in long run can be a big problem. Adrenalin/catecholamine can do some serious nasty stuff.
