So sorry it's taken me so long to reply. I'll try and answer everything in this one reply.
1. I'm up for about 16 hours every day and drink about 8 liters of water. It's really only a half liter per hour, and to look at how little a half liter of water is, it's actually quite a small amount. I just try and always have a water bottle handy and am actually very surprised at how much my body will actually drink if I've always got one next to me. I did a bit of research on acidic vs. alkaline foods. I'm not totally sure if this is why lemons help but from what I've found..any type of sickness whether it be the common cold to cancer can only live in an acidic environment. Viruses and whatever else cannot survive in an alkaline environment. Lemons are extremely acidic - however - when you eat them your body metabolizes it in such a way that it has an extremely alkalizing effect on the body. This might sound hoaky but you could mix a teaspoon of baking soda in a glass of water and it too will have a good effect on your body and it doesn't taste too bad (I do this once or twice a day if it's convenient). It's just high in salt so if you've got a health issue with salt, or already have a high salt diet it might not be the best for you. There's a ton of research on acidic foods vs alkaline foods. But it's important to know that it all has to do with how your body reacts to the food or beverage that makes all the difference, like how lemons start very acidic but in the body it's the exact opposite. Any food or beverage that has a alkalizing effect on the body is good for you.
Since the post, I started to drink green tea because I read it's good for you. I started drinking more green tea than regular water with lemon and I started to break out again! I noticed it took about two weeks for a breakout to really come through, then about 2 more weeks for my skin to get healthy again after going back to water with lemon.
2. Why did it take me so long to notice? I never drank much water to begin with...I only drank drinks like sport drinks, coffee, and other drinks that had water, but never just water. I think what led me to this realization is some reading I did about urine. Gross but hear me out. Your urine should be light yellow/clear and odorless. It was the focus to achieve healthy urine that led me to my increased water intake.
3. I'm not sure if I had cystic acne but some of my acne would stay beneath the surface, and grow in such a way that it was un-poppable. Some would end up being around for days or a week or two. I always wondered, what is this, why do I have this, why doesn't it just heal. There would be this hard blob under the skin that I couldn't do anything about - if I tried it would be even more noticeable. I'd end up with red areas that were mixed with normal pimples and hard blobs.
