okay speaking from experience, vacations seem to do that sometimes. i just returned from two weeks at a national horse show, and let me tell you temptations were high but i succeeded in staying clean. haha thats what i call it. anyway i have fell off the wagon before and i just go right into the high fat fast, the eggs, chicken and avacados thing for about 3 days and that will jump start your ketosis then back to induction until you are losing what you like is what i do. good luck if i can help let me know
