I'm with you on the tiredness, day 2 always wears me out, in fact I'm off to bed after I've posted this lol. Then tomorrow night and the next couple of nights after I'll be wide awake late into the night, always the same pattern getting into ketosis, once I'm in ketosis and settled, my sleeping returns to normal.
As for the toilet tripsI'm not one to be put off by too much info lol. Do you just drink your water slowly through out the day or are you bad like me and drink it in batches? When I'm good and drink it throughout the day the trips to the loo aren't as frequent, but as I struggle to do that, I often drink a litre at a time then have to dash off 20 minutes later to pay a visit.
Anyway day 3 tomorrow.... I usually hit ketosis on day 3 so hopefully it'll all start coming right. Good luck with tomorrow...lets get another 100%er under our belts x
