I get Laif 900 from my neurologist prescribed because of my migraines, as no drug of traditional medicine has been effective. At first I was skeptical that I could not see any benefit, but after a certain time taking the complaints were alleviated. When I had Laif 900 down again, because I thought I had fixed my complaints, the symptoms occurred after only a short time again. The alleged higher light sensitivity when taking St. John's wort I have not noticed, I could still without problems in the sun and got even a Spain vacation at the beach unscathed. And I'm a very light skin type with blond hair.
