Phentermine
"Today is my 2nd day taking this pill.  I have had dry mouth and was unable to sleep throughout the whole night last night.  I do not feel energy at all, in fact, since I didn't sleep, I didn't even want to get out of bed today.  I've had a bad headache today, and feel a bit nauseated too.  I'm going to keep trying it, but just wanted to go over some side effects after my 1st day on it.  I hope to lose weight though"
