Phentermine
"I started taking this medicine last week so I could lose weight faster and for the first few days the pills were working. They were making me not eat as much and I had a lot of energy. About 3 or 4 days later things got worse, I started getting very angry and agitated at everyone. I ignored this and thought it would go away, but it didn't. I started getting really depressed thoughts and it felt like I had to take this pill or my mood would get worse. The mood swings were getting worse so I put an end to this medicine. Wouldn't recommend this if you already have depression because it can make it worse on you"
