Excessive nightfalls :(

Guys, I need help... I have had 4 nightfalls in just 10 days. And it usn't something new I go through nightfalls very very frequently and I think that all my No-Fapping renders useless as obviously, my testosterones decrease after every nightfall. I think this is having a harmful effect on me. I have tried everything written in the internet but nothing works except for meditation (Brahamacharya or something), but I have had nightfalls after meditation too.
I think that I perform meditation wrong, I mean my pose must be wrong. If anybody knows some ways to stop these excessive nightfalls, please help and those of you who know the correct pose of the meditation to stop nightfalls kindly reply me... Thanks.
