i was like that too im on day 7 now and im feeling fine...just gotta keep going take paracetamol...go to sleep have a bath...read a book!!! drink all you water and more if you can! first three days are meant to be hardest...but i heard that if u had a massive crab binge before you start it can last a bit longer!
i think that the shakes are so vitiminy that is gives you a head rush too...but u get used to it!
keep going its worth it! join a team and read the success stories!
I'm on day 3 and I feel exactly the same, I have spent most of the afternoon in my pj's on the couch. I am starting to feel better now though so hopefully tomorrow will be fine again. Hope you feel better too
