UPDATE 6/12/15 (or 12/6/15 for the States)
The answer I gave below is rendered largely irrelevent and pointless because the question has been altered in such a way that there is now no mention of daily use. I'll leave it on in case the links are of any use though.
You're going to need a lot more than one aloe vera plant if you want to extract juice daily. Every time you want some juice, you have to remove a healthy leaf; obviously, if you do that every day, and your plant originally has 10 leaves, you'll have ten day's worth of juice and a dead plant if you remove all the foliage all the time.
Link below gives info on how to extract/use the juice, but there are plenty of places on the internet, including Youtube videos, which show you how to do it, just Google 'How to extract Aloe vera juice from Aloe at home' and plenty of others will come up
Here's another link, a UK one, but the info's the same apart from growing techniques - right at the bottom, it tells you that your plant should be Aloe barbadensis if you want to consume the juice fresh. It also gives a couple more descriptions as to how to extract the juice without the latex, which is highly laxative and probably not a desirable addition to your diet on a daily basis.
