Arimidex verses Tamoxifen who wins?

Hi Kim, I have only been taking Arimidex for 3.5 months and was so anxious to start.  Maybe this is too soon to feel all the effects but I've heard many ladies say side effects kicked in pretty quickly.  My prescription sat on the bench for 2 weeks while I waited to see my GP for his feedback. I read so much information I was petrified. He sent me to another clinical website which showed most of the clinical trials and resultant side effects were from women over 64, overweight and sedentary.  He didn't think I would have too many side effects - I have a B12 injection every 2 month (my body just doesn't make B12), high dose 25,000ic vitamin D capsule per week. I'm also taking calcium, glucosamine, vitamin C and magnesium daily.  And the big hitter is exercise. I try to do a hilly 5-7 km walk at least 3 times a week.  I already have a bit of bone density loss in my hip from having low vitamin D levels so this was one of my big concerns in taking Arimidex.  That will be monitored over the next 12 months but in the meantime I'll keep up the exercise and calcium.  I feel absolutely fine Kim.  Few hot flushes at night but at 55 I would be having those anyway!  No joint pain either. We are all different - I know some of the ladies suffer terribly and others like me are doing OK.  I was fortunate in not needing chemo or radiation, I wonder if going through this treatment makes you more likely to get side effects?  
So I now take around 8 tablets a day and I'm not game to change anything in case I break the magic combination!  I take my Arimidex in the morning after breakfast.  I am a terrible tablet taker, makes me gag as soon as it is in my mouth. My trick is taking the giant calcium and glucosamine in a spoon of yoghurt
