All suddenly slipping after an amazing month


I’ve recently joined and had the most incredible month of April! My goal was to make my lifestyle more healthy, and I’ve easily gave up alcohol, made major adjustments to what I eat, started cooking at home and getting up at 6am for morning yoga. I felt the best I did in the longest time! But after a month I all suddenly started slipping – I didn’t got up several times in a row and than out of the blue ate the whole box of chocolate cookie after having very little sugar all month, and more and more thoughts that I won’t be able to sustain this lifestyle are coming up. Any suggestions? And why all suddenly my mind is sabotaging me when I finally started feeling good?
