Help getting past day 2

So I've done Water Fast for 14 days repetitively for a while but now can't make it past day two. I got down to 98 lbs though today I sit at 104. I want to cleanse my system and mind again and to get back to 82 lbs. Any ideas to safely fast 30 plus days till Fathers Day. I was thinking maybe when I work doubles as a waitress.....and I'm past the 14 day Mark and hopefully below 95 lbs I will do a 10 cal juice. Only reason I ever broke the 14 day fast was I passed out at work. I'm 5 ft 7. Tweet
