I use adaptogens along side kava with no alcohol. And especially Rhodiola, Mucuna, and Tongkat Ali can give an energy boost like nothing I've tried and each day you're taking it only increases in effect for like 14 days then goes steady with slower improvements. I actually have to remind myself to rest because my mind gets tired before my body. Other to recommend would be Bacopa and Ashwagandha. Can increase attention, memory and actually increases synaptogenesis the formation of new synapses (dendrital prolifiration) so you can reprogram old patterns of behavior. Old yogis used this alongside yoga in India, and in large doses this stuff is just crazy as much as one suddenly can recognize of ones own patterns in behavior, emotions and thought. Makes me need less kava also which is nice, which is my point here. as well
