Energy

Does anyone have any recommendations for energy other than energy drinks? I feel like I’m in a constant fog all the time and it’s like all I can do to do like simple tasks throughout the day. I’m not depressed, I’m just groggy or tired. Is there some kind of vitamin or supplements that I could take to help improve this? Normally I’m such a happy, bubbly and peppy person but just recently I’m in this forever state of grogginess that won’t go away
