Welcome to the forum, Itsallgood!

You shouldn't be irritable, but you might feel tired. I felt tired for a week, but that got better and it hasn't happened again (I started Protein Power on July 29, 2002, and I've lost 31 pounds so far). I HIGHLY recommend that you read all over this forum. This place has been a godsend for me. Support, experience, information, answers to every question I had, positive affirmation. All here. Hope you start a journal too!

Best of luck to you!!!! Remember, this is a way of LIFE. I.e., it's permanent.

Best, Kypraia
