Drawing such a comparison would be difficult. But I would contend that before you try something like tDCS, you probably should try to optimize other easier and much more beneficial parameters such as sleep,diet,immunity,vitamin dosage,supplemental dosage etc. In the end a pocket tDCS device can really come in handy when something (GEB for example :)) gets really hard to understand.Its all about using it in moderation.
