All I can tell you is it gets easier!! Day 3-4 is still tough, you may not have got to ketosis yet. I'm starting week 5 and honestly motivation and setting mini goals has helped me. Stay strong you can do it!!
Hi hun i am on day 4 and i feel great ! yesterday was a killer i nearly ate my own arm just keep going and it will get easier i was ready to give up yeaterday but today after being weighed i have lost 8 lbs in 3 days !!!
I drink 3.5-4 litres a day, be careful not to go over board with water, it can be harmful, drink 3 litres see how you feel, if woozy light headed then rethink and drop to 2.5.
