Can you overdose on vitamin b? i saw a post that said too much b6 can cause toxicity but i thought vitamin b was water soluble

Taking lots 4 months: I think of overdose as a single high dose causing harm & taking a large single dose of b6 won't cause harm. However, taking high doses of b6 daily for months (usually at least 1000 mg but rarely as low as 200 mg) can cause toxicity symptoms, most commonly peripheral neuropathy (tingling & numbness), also headaches, fatigue & irritability, which usually dissipate upon stopping b6.
