The general consensus is that water soluable vitamins (B+C) do not present much of an overdose toxicity risk. You should be safe. Vitamin B is fantastic and I would recommend it to everybody. Here is the best B complex supplement that I have yet found:

Great, great supplement. You will see rapid improvements in mental state and energy levels. Cannot recommend this highly enough.

"Vitamin B" is a complex of several vitamins.
Of them all, Vitamin B6 is the one to watch the intake of.

Toxicity
Because adverse effects have only been documented from vitamin B6 supplements and never from food sources, only the supplemental form of vitamin B6 (pyridoxine) is discussed with respect to safety. Although vitamin B6 is a water-soluble vitamin and is excreted in the urine, very high doses of pyridoxine over long periods of time may result in painful neurological symptoms known as sensory neuropathy. Symptoms include pain and numbness of the extremities, and in severe cases difficulty walking. Sensory neuropathy typically develops at doses of pyridoxine in excess of 1,000 mg per day. However, there have been a few case reports of individuals who developed sensory neuropathies at doses of less than 500 mg daily over a period of months. None of the studies, in which an objective neurological examination was performed, found evidence of sensory nerve damage at intakes of pyridoxine below 200 mg/day (15). In order to prevent sensory neuropathy in virtually all individuals, the Food and Nutrition Board of the Institute of Medicine set the tolerable upper intake level (UL) for pyridoxine at 100 mg/day for adults (see table below) (4). Because placebo-controlled studies have generally failed to show therapeutic benefits of high doses of pyridoxine, there is little reason to exceed the UL of 100 mg/day.It is the mark of an educated mind to be able to entertain a thought without accepting it.
