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.

Provided original answer
You are correct that B6 is water soluble and generally water soluble vitamins are not thought to cause toxicity. B6 is the only one and no one knows why. But most people have to take really large amounts for months for this to happen.
