Hi there! Good luck on your journey. As to what to expect, everyone is different. I never experience the extra energy like the other ladies or the insomnia. I had been able to sleep just fine up until a week ago...not phen related.
It did make my nerves a tad bit worse, but that main thing is you will NOT feel like eating. So you'll have to make yourself eat throughout the day. There were times I did not want to put one thing in my mouth. Everyday is different. I'm here if you wanna chat. I've been on it three months now and have been doing pretty good with it. Good luck!
