Hey, Sounds like your there! They are typical signs of Ketosis, you may also start to feel thirsty all the time like i did and no amount of water will quench your thirst but it does pass. You can buy Ketostix from the chemist to test if your in Ketosis they are approx £4.50 for 50 sticks. You just wee on them and if there is a pink tint to the test area then your in ketosis. I wouldn't get them because if you stick to it they you will always be in ketosis. You may also get lots of energy too and may start to sleep better. Good luck with your weight loss journey, Nickie x x
