Extending the fasting period… day 3 of 7

So I’ve been chillin’ at about 155 for six or eight months now. My goal is still between 145-150, but these last 10 lbs have been a chore. To recap my eating habits, I’m vegetarian, no processed sugar or flour, and I eat for a 5-hr window in the afternoon or evening. I run 3-4 times per week.
The leap from a 19-hr fast to a 40-hr fast hasn’t been too hard, as I’m fasting one day per week now (10pm Friday to 3pm Sunday, for example, fasting all day Saturday).

So now I’m making the leap from one day per week to a one week fast!

This isn’t my first ‘long’ fast but it’s been a couple of years, so I wasn’t sure how the experience would go. I’ve been feeling generally good except for a bit spacey and physically tired. Any “hunger” I’ve had has just been the habit of eating at a certain time and I’m not getting any detox headaches or bad breath. (I’d like to think that’s because of a generally good diet?) I was noticing that the skin on my abdomen is much warmer than the rest of my body; something going on I guess. During my last long fast I remember continually checking up on myself, how I was feeling, what symptoms were showing. This time around it’s much easier mentally, knowing what to expect. I have to travel tonight unfortunately but after tomorrow I’ll be able to relax at home with no major outside demands on my time or energy.
My goal is to water fast for 7 days and to at least get into under-150 territory so my body can see what it feels like. However much I lose, I expect to gain about half of it back within a week or so as my glycogen stores recover. I’m not fussed about exact pounds lost or number of days fasted though – I’ll see how it goes and break it earlier if that seems to be in order.
Other goals: reach that state of goofy, beaming well-being that longer fasts bring! And hopefully some of my nagging injuries will heal up; I’ve got a wrist thing and an ankle thing right now.
And in strict honesty I’m not drinking only water. I’ve had herbal tea (decaf) and a couple sticks of sugarless gum. Not ideal, but the small cheats are helping me through! (Plus, without gum my ears pop on airplanes.)
Best wishes to everyone out there who's sharing this journey!
Cheers
