I have been on tamsulosin for six years now and the tiredness and lethargy are getting worse! Would Vogel's Prostasan Saw palmetto be a good substitute??

Prostasan will work best if you have a mildly or moderately enlarged prostate. If this is your case, the answer will be yes - you can substitute this product for tamsulosin.

However, do not stop any prescribed medicines without the knowledge of your doctors.

In addition, it will be worth pointing out that your prostate symptoms may worsen for a short time after you stop tamsulosin and before Saw palmetto gets a chance to start working.
