[Q]: This book came out a long time ago. I read it when it first came out and it introduced me into the world of ghosts and and lore. I was 12 years old then in 1982 and even now when I pick it up to read....it still takes me back to the feeling...when I first picked it up and sent shivers down my spine...in a fun way of course. The stories and the drawings were perfect together. A great book. I have all 3 volumes now and I hope he comes out with a 4th one soon.Thanks Alvin and Stephen for scaring the pants off of me when I was 12.

[Q]: I do not write reviews typically but this product changed my life! My periods have always been irregular, however I still did not expect them to just stop when I was 25.. I suffered the mental agony of never getting periods unless I took Provera when I decided enough was enough. The wise Internet came to my rescue and convinced me that Vitex could be the solution. I started taking this product once a day (first thing in the morning) for 120 days (2 boxes) with a gap of 2 days when I forgot to pack it on a business trip. During those 120 days, I got 5 periods (spotting, very light to light flow). Then I decided to give myself a week's break... and got my full fledged period. So, so thankful! If your doctor says everything's okay with you (yeah, right) BUT you just need Provera to get your period and fertility treatments to have children, I HIGHLY recommend you try this product. Just give it time to work. Good luck!
