There is much posted online about using higher levels of b6 for dream recall as well as to help with carpal tunnel symptoms. Be careful many of the postings I've read don't mention toxicity. For dream recall they recommend 250 mg at night. I believe this exceeds the safe upper limit recommended for B6 supplementation. I learned this the hard way. Tremors and twitching ensued until I researched and realized what was going on. Be careful and do your homework before adding any supplements.
