Update. I'm still loving this product. Energy is insane. I took the weekend off from taking Oxy Eca. Monday morning I started back. I got kinda nauseous after I took it. The nauseous feeling eventually went away and hasn't come back. Man this stuff kills my appetite. For me this is right up there with SX when it comes to appetite supression without the side effects of SX. I guess I'm a good responder. I'll weigh myself Thursday or Friday and report back.
