I am just curious what form of B5 are you taking, I am taking the powder from Acne-miracle.com, at 10 grams a day and I feel fine, in fact I find I have more energy. I simply mix it with water or my favorite fruit drink. They say, with the information packet I recieved with my B5, that you have to be choosey who you purchase your B5 from, they say that B5 too can expire or go bad in different heat environments. Jut like milk, it is good for you, but in different heat environments-- can cause stomach irritation and nausea. And sometimes may not work at all, if its bad or outdated.
I have had cystic Acne (the severe case) and with only on my forth week, the redness is dramatically decreasing and the cystic acne are draining faster and disappearing. With the dramatic results Ive seen in only for weeks, I am very excited to see how I look in another 4 weeks, they say you have to be on B5 (10grams) for 3months to have total clear skin, I just cant wait to see how I look in another 8-10 weeks.
Dude I hope you stick to B5, because it is working for me what antibotics and creames did not accomplish. And its all natural!
Good luck, and look into researching how B5 can go bad or expire.
