Lecithin Question

How long can/should you take lecithin supplements for? I've been taking a 1200mg supplement daily for about 2 months and am wondering if I should take a break. But I've also seen that some people on this site have taken it for extended periods of time.

Also, is there a significant difference between 1 1200mg capsule daily and 3-5 tablespoon fulls of the granular form?

Thanks, Rotgut
