.. I can't suggest u keep going with ur fast as it could be something serious (so better to be on a safe side).
OPerhaps u are too toxic and may be it is better to stop ur fasting and just start eating Healthier and in a while repeat the attempt.
When I was on day 2-3 of my 14 day Water Fast I have couple of attempts of vomiting but nothing came out (ppl say it is the sign of detox)... in ur case it could be not something very welcoming... and as u can see none of the experience fasters replying to u.. so I guess it is better to take a break and re-feed urself in a correct way and then return to a Water Fast IF it is really necessary.
Here are 2 post of mine about whether all ppl should be into raw food. Read it - quite informative. ;)
