[Shock]

Hello all. My birthday is on October 31st and I decided to go on a water fast for 30 days. Mostly it is because of the weight loss (got out of a relationship, was depressed about a lot of different things) and I was just basically drinking beer every day and eating nothing but fast food and gained about 30 pounds. I read online that water fasting is safe (for those who think otherwise) and is recommended not only for weight loss (that's just a bonus) but to basically reboot your body and get all of those toxins out from the months I have been gorging on unhealthy food and alcohol. As of today, I am on day 6 (started October 1st) and I am not sure if anyone in this forum has been through this before but I just want some motivation because it is hard lol. I mean, I do not feel hungry anymore, but I do still have cravings. The first 1-3 days were horrible as I just kept hearing my stomach growling and begging for food. Day 4 was a little better but I had so much stomach acid built up that I could not sleep and actually had to throw up. Day 5 I woke up for work exhausted (not because I was sleepy but my body was just out of energy). I took a 20 minute shower and was just completely drained. I could not even dry myself and put on clothes without taking short 20 second breaks to catch my breath. However, I believe this was the day that my body entered ketosis because by the afternoon I had a lot of energy. Today I woke up fine and normal as if I ate breakfast and still feeling good right now, but I work in a small office where co workers constantly eat in front of me. Like I said before, I do not have the sensation of hunger anymore and my sense of smell (because of this fast) is extremely high so I basically smell all the different types of food they are eating. It is giving me a huge craving to eat lol. My question is, has anyone done a water fast here before? If so, how long did you go for and what kept you motivated in times where you were at your lowest point? Thanks for the insight.
