intermittent fasting week 1 session 2

Today I had to settle for an 18 hour fast (still good but for fat burning purposes not as good as 24 hours). I had to go get glasses and I know for sure that I can't handle a car ride when I haven't eaten anything because I tend to get dizzy. I realized that a fast that last from 6 p.m.-6 p.m. is a lot easier then 9 am-9am so I will try to do them later in the day. According to eat stop eat fasting once a week is good enough but I will try to fast from Friday 6 p.m until Saturday 6 p.m but for some reason Saturday happens to be the day where my family goes out so I will settle for an 18 hour fast if I know something like that will happen. The fast is getting easier but I'm going through a withdrawal from not eating like I normally am so I'm not getting the boost of energy that others claim to have from fasting. It is still early so I will just simply have to keep going. as for my weight I am still 136 pounds and my measurements doesn't seem to have changed much.
