Research further.
"Most people claim they do, but I have not seen any research to support that. In fact as I mentioned to you those drugs are really SERMS: estrogenic in some tissues and antiestrogenic in others. I did a little research on the two mechanisms whereby estrogen induces water retention (increases in antidiuretic hormone, or AVP, and aldosterone) and discovered that for AVP, tamoxifen is actually an agonist, just like estrogen, so should enhance water retention by that route:

I haven't found any studies on nolva/clomid and the renin-aldosterone system yet.
Updated Note: Here is one showing no effect on renin and sodium excretion with tamoxifen. So the increase in AVP should lead to water retention from nolva since there is no effect on the renin-aldosterone system:

I would say based on what I've seen of the research, you are better off sticking with an aromatase inhibitor to help fend off estrogen related bloating."
I don't understand why they would even recommend nolva during a cycle that had mostly androgenic properties. If if was anabolic qualities such as Dbol, Drol, or Test then yes for gyno prevention.
