Sadly I am in the same position. I want to better myself, loose weight and stay on track but sometimes the smallest thing will deter me from completing my goals. I feel my weakest influence isn’t energy it’s the negativity of others. I use to be drained all the time mind you, from doing daily tasks and working two jobs, but then I began taking super foods such as spirulina and chlorella! It has immensely increased my energy and it’s all natural, wheatgrass is good as well. Do your research first but I guarantee you’ll have more natural energy ! Detoxing is also a good way as well as drinking more water, sometimes we are tired because we’re dehydrated~
