http://www.chaserenergy.com/ This stuff is available at Walgreens for $4.99 for a 2 bottle pack. I love it and after being B12 deficient, I can see why it would work. It lives up to every promise on the bottle.
I am taking a bottle with me to the doctor on October 24 to see what her opinion is of it.
With my gastric bypass, things dump into my system so fast I almost alway get the Niacin rush they speak of. About 5-10 min of red skin, hot flash feeling, sometimes itchy. The first time I took it, everyone at the table said I looked beat red.
I just took a bottle so that instead of sleeping I can enjoy the kids today. I could use a nap and will likely go to bed early tonight.
