COMMIT: Commit to long-term lifestyle change. It is a marathon, not a sprint. Get help from nutritionist and coach. Do not rely on diet pills. You don't say how overweight you are, but losing 1-2 pounds a week is usually sustainable and healthy. Do not starve yourself ("no food") because that will in the long run harm your body. Groups like weight watchers, oa, and tops can help with accountability.

Always: See your doctor to find out why you have an impaired memory. Avoid all drugs and alcohol (dope makes people gain weight), make sure you are not pregnant and find out why you are nauseated. Find out if your headaches are stress related (stress causes weight gain) and put together a weightloss plan for the long term and consider having a maintenance phase in it.

Weight & Frustration: First, diet pills don't work and are dangerous to your health. Please promise never to do that again. Second. To provide you with a valid answer here rather than just preaching at you i need a full week food diary. These are now simple and you can find one of a number of websites where you can enter the food and it calculates the calories and types of calories. Food diaries are very important.
