Welcome Doppleganger! It's good to have you here! I'm new to this too, but have also been doing tons of research on the topic as welll, and I agree that you're moving in the right direction - for you and your mum!!
I will say from my own experience, that I find it much easier to stick to if you strive for 100% raw rather than allowing leeway - those leeways wind up opening floodgates for me. I'd been doing well for the past four days then last night, family stress hit, and it was pizza at midnight

I'm back on raw today - I think that's the most important thing - don't let the cooked stuff snowball you away from raw. If you indulge in cooked food every now and again, get right back onto raw.
There are many, many opinions on the best ways to go raw. Find the one that best suits you and stick with it. I like the Taliferos best of all - they don't use dehydrators or dehydrated foods (
www.thegardendiet.com), and also love Patenaude's stuff too (
http://www.fredericpatenaude.com/). Roger Haeske is another good one I've found (
http://www.howtogoraw.com/). There's quite alot of free helpful info on their sites, as well as things that can be purchased. The Taliferos have also started a raw vegan channel online which I think is excellent

There's a link to it on their main page for their Raw Paradigms channel ($10 per month -or pay per show downloads $2 - $5).
I like keeping it simple mainly, with a good raw vegan recipe evry few days, like an herb salad, raw pasta or raw vegan tacos. I find it's good to break it up. When I first tried to go raw I went all complex and thought going raw meant gourmet everyday...who has the time??? That attempt failed due to time and financial constraints. The next time I kept it simple - just pick whatever my fancy in the produce sections, cut it up and eat it. That attempt failed because I panicked - my husband said he wanted to go raw, but then I noticed that I was the only one eating the raw stuff - so I started cooking again to get him to eat, and once again fell off the wagon. This is my third attempt this year, and hubby says to not worry about him. He does want to go raw, but he's very addicted to cooked and processed foods (hence the pizza last night). So, I guess I get more determined each time, and just take it day by day.
I suffer from invasive candidaisis. It's when the yeast cells in your body take over and hammer your major organs. My liver and kidneys have been taking a beating for some time now. It can be fatal if left untreated. I was made aware of this by a Chiro-vedic doctor I was seeing last year. He took me entirely off caffiene, wheat, and sugar, and was pumping me full of probiotics to kill of the candida. I went from a score of 4 down to 2 in six months, whereas a healthy person is around .50 - 1. I felt good - I was walking over 3 miles per day, meditating, and losing lots of weight. But then life got in the way and he moved his office too far for me to reach, all those healthy habits fell away
I also have developed some rather suspicious looking moles over the years that my new doc wants to remove and have tested for cancer. I haven't been able to afford the co-pay ($300) but hope to have that soon. I can tell from the past week of going raw that my yeast cells are running amok again, but I know that if I can get to and stay 100% raw, that will be corrected.
Best of luck to you in this
