Does water fasting help with addictions?

Hello

I'm Water Fasting again, and trying to kick a caffeine/nicotine habit. It's very difficult, and I'm wondering if its worth it to go this route.

I've read around the internet that it can take 1 week to 6 months to completely get over caffeine addiction. Does Water Fasting speed up this process?

I'd appreciate any personal experiences if you care to share. Thanks!
