My problems on the veganized 4HB diet

Well well well, I have been on this diet for almost 3 months now, with little success. Not because the diet doesn't work (I guess it does), but most likely because I didn't manage to adjust it to my vegan lifestyle.
I don't consider I have wasted my time, but there are some things that necessarily need to be fixed.

1. I don't get enough protein if I don't add excessive amounts of tofu. I like tofu, but I think my body doesn't like it as much as I do. Also I think it's a food that in this diet is kind of "forbidden", so then I am cheating every day big time :(
2. An alternative is eating huge amounts of beans, and definitely that it's not good for me either. Let's put it simple: I have so much gas that I could fly ;)
3. I have managed to find comfort food, and I abuse of it. I prepare a chocolate tofu pudding I took from the vegetarian south beach diet, and I just cannot stop till I finish the whole thing!
4. I snack a lot, and specially nuts. I'm going nuts for nuts! Now I try to eat only 15 cashews, but I swear I could eat the whole bag. Or devour the whole PB jar.
   
5. I don't have enough energy in the gym from day 1. Definitely that is really bugging me. Now I cannot even run for 5 min without panting. I don't like the idea that I am probably loosing shape on this diet. I used to go 5 times a week and now I go only 3, and hardly.
   

So I am trying to get back on track, but it's not going to be easy. I have acquired some bad habits that it would be difficult to get rid of. I'm thinking about doing 2 more weeks (that would be 12 weeks total), and then go to South Beach diet phase 2 but keeping breakfast of 4HB (rice protein shake on almond milk plus tofu scramble). Then I can start planning on starting over on 4HB later on.
What do you think?
