What would be best to take in conjunction with Alli; Hydroxycut, or Greet tea + Hoodia?

I have been taking alli for about 2 months now. I have been cutting back calories and exercising more frequently, but I still feel like I have low energy, and sometimes too tired to work out. I've lost about 15 pounds so far, but starting to plateau, I want to add Hydroxycut to give myself a jump start, but also considering Green Tea and Hoodia, since they're more natural and probably won't make me jittery. What do y'all think??? Do not bother replying if you're just going to say "DONT TAKE PILLS!"
