Great to hear you liked it! It's incredible what can be achieved when we give body a rest and cleanse it with healthy fluids. Losing weight is just a side effect, the main thing is that it removes toxins and allows the body to heal itself. I'm engaged in a raw vegan/fruitarian community and have heard countless, mind blowing stories about such transformations.
As for the juice fast, you can read two articles I previously posted. I would suggest to start slowly, maybe try 2-3 day juice fast for starters, or simply incorporate one fresh juice as your daily meal. After you are more comfortable with it and you started eating more raw fruits and veggies, then you can go on a prolonged fast. I won't judge you if you want to jump into it straight away haha, but there might be more detox symptoms when someone who eats relatively unhealthy jumps into a fast without transition. It can also be dangerous if you don't properly break a long fast. Depending on how long it was, you should slowly ease back into eating - first by eating water rich fruits, then adding salads and eventually moving back to some more dense food.
Do you strain the liquid after blending? If not, then it's more of a smoothie. Unlike juices, smoothies have fiber in it which means digestion is still going on so it's not the ultimate healing. Juices go straight into the system - no digestion. Smoothies are excellent as well, of course, they just have a slightly different purpose.
For a day of juicing a minimum is about 4 liters. I used to drink 5-6l which is quite a lot, so it takes some time and money to do it properly. Basically, whenever you feel hunger you drink juice. :)
If you are on IG, I saved a highlight with some juice recipes I made during the challenge. I can also point you to some other people who documented their fasting journey if you are interested in learning more about it.
