i feel this is just to much.
Really? Why would you think that a healthy guideline developed by the plan you've chosen is too much? Have you researched how many calories / points you need to be healthy?
At 219 pounds, you should be eating around 2000 calories a day to lose weight at a safe and reasonable rate. By ignoring the advice given to you by Weight Watchers and eating only 16-18 points, you're only eating around 900 calories a day - less than half of what you need.
No wonder you're hungry, feel sick, have headaches and so forth. You're starving yourself. And I'm dead serious here. A 900 calorie diet is less than prisoners in many Nazi camps were fed.
Honestly I don't meant to be harsh, but I don't understand why you would choose a diet plan to follow and then proceed to IGNORE the guidelines they give you for healthy and safe weight loss because you "think" it's too much.
Please start eating more. You're not doing yourself any favors by starving yourself.
