Howler, I really had no doubts that I wanted to try it! I couldn't hurt me to try it, if it didn't work, it would be no diffeferent than any other diet aid, but still I tried it and it worked. You can see from my blogs and pictures that it is working and I am working it.
I think the diet plan you have mentioned being on before sounds depressing and scary. I have done the low calorie thing before but never that low. I am sure your doctor was watching closely, but still I can't imagine it.
I think if you use SparkPeople and Sensa combined you will succeed beyond measure. Both items are great, but when combined I think that makes a big difference. Especially if you are going to need help with meal planning in larger quanties. I think try their meal planner and customize it as needed and then sprinkle everything and you will be on the road to not only success, but true overall health!
Wish you the best on your journey! Please let us know how it goes and don't get discouraged!
