Premarin and premarin

I have been in surgical menopause for 3 weeks now. I was put on Premarin .6 mg 2 weeks ago. For those last 2 weeks, I have been so constantly nauseous, occasionally vomiting. I'm lucky to eat 2 pieces of toast & a cup of tea each day! Still having hot flashes, not as soaking wet as before but still pretty uncomfortable.
Does anyone have similar issues?

I am 52 and had a hysterectomy at 28, so I've been on lots of different kinds of estrogens in that time. Once I went on Premarin until I found out that it is made from pregnant mares' urine ( the "mar-" in the name of the med). They are confined to very small stalls and have catheters to catch all of their urine. Many of their colts are born unhealthy, which is no surprise. If this disturbs you, remember - there are LOTS of good alternatives.
I'm trying what are known as "bio-identical" estrogens next this summer.

I am taking .65 mg premarin but still having sever hot flash's and mood swings. I was on the patch but the adhesive made me break out and I could not wear it. Does anyone know of any tablet form of hormone replacement I might try. These hot flashs and mood swings are drivng me crazy!!

Thanks!!
