Weight Loss Formula No.1 - Headaches or irritability
If you are experiencing a nagging headache or irritability, and you feel it is due to the product, you should stop use immediately and consult your physician for severe symptoms.
Keep in mind, it's possible you have changed the types of foods you are eating and have decreased the amount of caffeine and/or sugar you were consuming.
Regular caffeine consumption reduces sensitivity to caffeine. When caffeine intake is reduced, the body becomes oversensitive. In response to this oversensitiveness, blood pressure drops dramatically, causing an excess of blood in the head (though not necessarily on the brain), leading to a headache.
This headache, well known among coffee drinkers, usually lasts from one to five days.
Often, people who are reducing caffeine intake report being irritable, unable to work, nervous, restless, and feeling sleepy, as well as having a headache. Sugar withdrawl may cause the same symptoms.
With that said, it's very hard to determine if this is the cause of your complaint, so if your symptoms persist or are severe, it's a good idea to consult with your personal physician.
