I have almost always slipped into ketosis effortlessly, feeling great all the time, better in ketosis than out of it, generally.
I have observed other people taking about 2 weeks to adjust, but I often wonder if some of the symptoms which we attribute to going into ketosis might not be more likely candida die off.
I am not at ketogenic level every day. But I have been in ketosis almost every day for the last 5 and a half years, and the only changes I have observed in my physical condition have been vast improvements.
