Can you drink weight loss/energy boosting drinks while on phentermine?

I started taking phentermine for about 3 days know and my appetite hasn't changed. I wanted to purchase Body Effects by power performance but I am a little worried that it may make me feel sick. The label for Body effects states that it is a appetite suppressant, mood enhancer, energy booster and a fat burner. The phentermine pill alone doesn't make me feel jittery at all. I am drinking about 1.5-3 liters of water a day and I am trying to consume 1300 cal and I exercise about 2-3 days a week. (im very busy) Has anyone tried Body Effects? It is not a meal replacement/protien shake.
