i fasted yesterday using the lemon juice, maple syrup and cayanne (master cleanse) method. i intended to do it for 3 days but i had the same reaction, even throughout the day i was weak and my vision was getting messed up (lots of 'stars' and darkening of vision). i have hypoglycemia and i think that was a huge part of it. do you have these symptoms if you dont eat for a while anyway? if so you probably have hypoglycemia. personally, i dont think straight up fasting is good for my body, a juice fast or something might be better. ymmv
I don't know if I have hypoglycemia, but today I had moments of the darkening vision and got stars or "cross-eyed vision" every once in awhile. It passed quickly and only happened once or twice.
A couple years ago I did the lemon juice/cayenne/maple syrup for two weeks. Amazing mental clarity, more free time when you aren't preparing 6 meals a day, greatly improved memory.
My memory has been shit today--I even left the lights on in my car causing the battery to die! But, that has happened before... Lol.
Yeah, plan on following through. Because you are likely to feel crappy at some point during the fast, most likely the first three days or so. The enlightening, cool mental and physical effects don't show up until after the initial detox usually, but as with anything ymmv.
When I woke up this morning, I had the most unpleasant and unusual taste in my mouth. Almost metallic but not quite. Totally made me not want to eat anything this morning. So I didn't. When I got hungry around 10a, I knew if I ate then, I'd be hungry around noon and again around two... And I didn't have enough food for all that eating. So, when I got hungry at ten, I told myself "Just last 'til 11." At 11, "just last 'til 12." I've gone all day so far (it's 5p) without food. I don't feel very good, though I don't feel bad--Just a bit cold (I'm always cold though) and weak. I'm going to see if I can make it through tomorrow with everything I need to do--If not, I'll eat something light. The main reason I want to stick with this? I've been over eating lately and I think this will be great to get me back on track with getting me down to 120 again (I gained 10 pounds when I stopped smoking). I'm not doing this for weight loss, but to jump start it. Waking up after "binging" with a horrible taste in my mouth wasn't cool. Yes, I brushed my teeth after eating. I didn't really "binge," but for me, I did. I had three or four pieces of fruit around 8p, then while cleaning up the kitchen, I ate about two cups of (cold, plain) pasta. I need to get these urges to eat uncontrollably under control--I did not need the pasta, but I wanted it.
/Rambling. Wish me luck for tomorrow!

The biggest issue I foresee is having all this time not spent preparing food, lol.
Edit: Yeah, I caved. Oh well! Now I know it is possible for me to fast without ripping someones head off.
