Anyone taking low dose Tamoxifen for high risk chemoprevention?

I am a post-menopausal woman who was recently diagnosed with LCIS, a high risk condition, and was offered the usual chemoprevention choices of tamoxifen, raloxifene (Evista), or exemestane. I would like to do what I can to ward off BC, but I find the side effects and risks of these drugs daunting, especially since I have a number of pre-existing conditions which complicate matters.

I saw a thread on this site for women considering low dose tamoxifen (10mg, 5mg, 2.5mg, 1mg or alternate day dosing) which had some good links to studies that indicate that lower doses of tamoxifen than the standard 20mg may possibly be effective. Most of the women who posted already had BC and were taking anti-hormonal drugs as an adjuvant treatment. Some were intrigued by the idea of low dose tamoxifen, hoping to reduce side effects, but many were not comfortable (or had docs who were not comfortable) changing up a treatment which is the standard of care.

This leads me to ask if anyone who is on chemoprevention for a high risk condition has talked to their docs about low dose tamoxifen? I understand that many who might benefit from the risk reduction of anti-hormonals, choose not to take one due to concerns about risks & SE. However, taking something seems better than taking nothing to me, so I plan to ask my doc about low dose tamoxifen. I'm particularly interested in hearing from anyone who has taken a lower dose of tamoxifen -- what dose did you decide to try? What was your doc's reaction to the idea? What has your experience been like
