Ivan_P I took the supplement for two months but did not notice any particular difference. Rather, I realized that my positive comment about Xalatan was incorrect. The reason it seemed to work for me is that I had been playing some games on steam that I found gave me less migraine problems even without drops, compared to using the PC outside of steam games.
This explains why the drops seemed to work with the PC but not with the new company car that kept giving me major problems.
