Can caffeine will deplete your body of vitamin b; is this all?

Yes & no. Caffeine acts as a diuretic & makes you urinate more. B vitamins are water soluble so you might potentially lose more b vitamins while you urinate. But realistically, this loss should be negligible, similar to if you drink a lot of water and have to pee it out soon there after. Alcoholism is different in that alcoholics tend to drink alcohol to exclusion of most other nutrition & vitamins.

Just wondering why caffeine does not seem to help me wake up or have anymore energy? It seems to relax me. Same thing with b vitamins no energy. Why?

Your low energy can be from thyroid or other hormone imbalance, depression, or something else. Start w/a fist to your doc and then perhaps a mental health professional. Peace and good health.
