I really, really hope you're joking.
I took something called Oxy Elite Pro. Is to accelerate your metabolism, loose weight, reduce your appetite.
What is does is to accelerate your thyroid, the gland that controls your metabolism and several body functions.
What those pills (and many other substances like the 5 Hour Energy drink) is to cause hyperthyroidism. The hyperthyroidism causes anxiety (excess of energy), lack of concentration and depression.
I took the pills for 4 months thinking "I had it under control" and I was thinking my stress was work related as I work in a TV station.
I was not able to concentrate, I was loosing my nerves very easy and I was starting a relationship with a girl and we had huge fights. I even started to cry when I was at my studio and my supervisor was getting nuts because I was not achieving anything. And that was after stopping the pills a month before.
I realized I had a depression pattern, you have to add the crazy work environment I created and not the braking up with the girl.
I had to backed up everything. I stopped to even take the protein milkshakes. All that was September/ October. It was until February where I was more stable. My now, ex girlfriend contacted me again in February and on March I exploded again with a jealousy attack.
Right now I am feeling better, I am doing great at my job, still very calm and the girl is hiding from me. It took a long time to balanced my body again and I can sense it.
So... what ever you take, read the ingredients and do a research. Do not take anything to accelerate the metabolism. People do not noticed as I didn't but look at how they work and go to Wikipedia and look fro
