Only 375 mg / day which is a typical size of one pill of standard additional nutrition - so no real medicine. Like said, it could be a coincidence that it all dissapeared the day after I started to take them.
Anyway my clusters have always (~once / year, > 30 y => lot of experience...) lasted 6...8 weeks and they've always behaved like gauss-curve => starting slowly and reaching the heights in the middle and then slowly fading away. Now it stopped after 3 weeks at the top of the curve. I don't have any other explanation. What I also noticed is that the tense in the face and sculp (left side) I normally have during and before the clusters disappeared. This all I've had now over 5 weeks since it went away.
And not to forget the other minor things as well; the rest of the positive effects.
