Be careful eating too much soy, not good for those with thyroid problems. I used to drink the Revival soy drink and it helped my hot flashes, but only for about 3 months, then it was back to hot flashes as usual.
This company makes soy products that really help with menopause. I bought 15 bars for $35. I ate 1/2 to 1 bar a day for a month and it really helped reduce my hot flashes etc. This was recommended to me by many friends and I now eat these weekly. Taste great, full of vitamins and really works. Check out the web site for a special introductory package.
