I started on the same day as you guys and I'm really struggling at the moment! Morning of day 3 and I can't concentrate on anything, it's like my brain is running at half speed. No cravings though, just hunger!
I went a bought some ketostix this morning to cheer myself up and mine are moderate pink already. Hopefully that means I'll get the increased energy tomorrow that I've seen people talking about!
I love finding people who started at the same time as me, I'll be reading your thread every day now! Good luck!
