Starbright. I hope that you find some relief soon!
I would be helpful if you shared with us what your former diet was. For instance, switching from a processed food diet or a meat and potatoes diet to a 90% raw 100% vegan diet quickly could certainly be a daunting task.
Is there a specific raw diet you are following? Are you juicing, drinking green smoothies, salads, nuts?
As far as your husband goes. Yes, I think weight loss is a fairly neccessary part of this. If only because (depending on previous diet) the colon alone contains lots of undigested matter. Also, the body has stored a lot of toxins and the common understanding is that it will generally detox first before it starts taking in lots of better nutrients. However, there are things he can do. If he is active, he may want to eat a fair amount of fruit. He should also be doing daily workouts and yoga, to keep muscle tone during the transition.
Have you read any books on raw foods? Is there an author that you gravitate to? They may have some help. For instance, David Wolfe lists several remedies in his
Sunfood Diet Success System. A website your husband may want to look at is
