I want to be energetic

Hey everyone! I am working for a software company for last two years. I was very energetic person. But now I feel tired and drained all throughout the day. I used to take a lot of energy drinks as I want to be part of every activity that happens in the office. But I am not able to make it. Last day I told this to my friend. She told that she was noticing this for last few months and she was about to as about an acupuncture treatment from a clinic in Toronto, which can help me in regaining my energy. Is this acupuncture safe to take? Will this have any adverse effect? How long is this treatment? Is there someone who has undergone this treatment? It will be nice if you can share your experience!
