You would be amazed at the incredibly negative things lack of Vitamin B1 in your system can create. It's especially important for creative people because that creative energy will burn up the B1 in your body in a red-hot hurry!
Yes, it's not the whole answer to whatever ails you, but it surely helps. I take 200 mg of B1 and 500 mg of Vitamin C twice a day and it keeps me revving along. Even if you take a B complex, make sure to take some additional B1 and C.
Once you have that vitamin soothing your nerves (and it does) the other stuff life throws at you is easier to handle.
Hope this helps!
