Hi Jade,
I also have trouble getting up in the morning, unless I have something to do like catching a plane. Last Saturday morning, I tried "Get Around Too It" (Part A, because I hadn't done it before) to see if it would help me "get to" a number of really hated tasks -- and I was up and doing them in no time! It was amazing: I accomplished two tasks before realizing I had actually gotten up early on a Saturday to do housework! 
I haven't tried 10 Minute Supercharger in the morning, but it seems like a good idea. Why not try it and see? I plan to.
As for creativity, I write, draw and sculpt and, like everyone, sometimes I dry up, sometimes right in the middle of a project. Have you tried Image Streaming? I learned it from Win Wenger's book The Einstein Factor, and it can be a great help. I particularly like the "leaping over the wall" exercise. (As you likely know, Dr. Wenger has collaborated with Paul Sheele, but I haven't gotten Genius Code so can't give you any input on that.) I also find that when I'm feeling down on myself my creativity goes into hiding. "Self-Esteem Supercharger" has helped in this area. "New Option Generator" and "New History Generator" also help with creativity because they encourage me to use my imagination in specific ways, and this leaks over into other areas.
I strongly suggest you avoid thinking of yourself as someone who "used to be" an artist. "Once an artist, always an artist" is a cliché but a useful one.
As for getting back into it, probably the most helpful advice I've ever received was from a drawing instructor who said, in essence, "Get out a big piece of paper and put something on it. It doesn't matter what. A line, a dot, a squiggle. Anything. Then keep it up until you've covered the entire page, from side to side and top to bottom. It may well look terrible, but that doesn't matter. While you were drawing, you were getting into the swing of drawing." Try it. Force yourself to go on and before you know it, you'll have finished a piece. The first one will probably be dreck. Give yourself a limited time frame to go back and fix it as best you can, and then without thinking about it too much, go on to the next project. Before you know it, you'll be much happier with your creations, you'll be able to give more time to conceptualizing them without getting down on yourself for not being creative enough – and the most important thing about them is that they will exist!
Good luck, Jade,
Danielle
