My weakness etc went away at the end of day 7 roundabouts however I have noticed a couple of threads by long timers who have complained that they are sick every now and then. Maybe your body goes up and down. Plus remember your immune system will be slightly weaker on this due to not eating as much as you used to. Even though all the vitamins is in it. I had to come off before coz of a chest infection drs orders. However I wish I never listened to him as I enjoyed food to much to come back on again and if took me a year to get back on it again.
Think I am getting a bit of a chest infection, so might avoid the doc. I am only doing this for four weeks and then one week refeed then mam and dads 50th anniversary and I will decide then whether or not to come back or do SW
