Juicing and anxiety

Hi all,
Im now in week 4 of juicing 4 pints a day of organic green juice,I feel emotional and anxious.Could it be coincidence ?
It seems to be progressing and I have suffered from anxiety before although Im not sure what the "cause" of this episode is .I want to stay on the juice(i eat normal foods too up to 80% organic)as my body needs the help as I have eaten so badly over the years and abused my system with alcohol and drugs etc.
I believe in the power of juiced nutrition but am now enjoying the emotional and anxiety that im going through-any thoughts?

Thanks
