I am on day 22 of Ideal Protein. I have lost 14 pounds in the past three weeks. I know that initially, you can have some nausea. I suspect your increased salivation may be a similar symptom. You will most likely get a really bad headache on day 3,4, or 5. This means you are going into ketosis and your fat burning switch has been turned on!!! Yay!! My headache only lasted until the tylenol kicked in. I am noticing lots of extra focus and energy. I have not taken a nap the whole 3 weeks I have been on the protocol and I sleep like a baby. Stick it out. Week one and parts of week two are tough! You can do it. The results are so fantastic!!
