ive only done about 2lts today but i literally cant drink any more. feeling really tired 2 and i shouldnt as i had a great sleep last nite. however as i binged on sat and sun and have been 100% ever since, can guess that im prob heading into ketosis which is why i feel so crap! got another hour left at work and i just want my bed!!! (takes childish tantrum, stamping foot on floor etc..)
