HeB menstrual complete

Has anyone tried this brand? I just bought it and it works good for period cramps but I’m so sleepy I feel like in on a cloud . I was wondering why I was so tired yesterday like overly tired. I couldn’t even function and then I read the package and it said drowsiness may occur lol and I took it again at night when I slept through the entire night and had several dreams lol which is crazy because I have problems with waking up in the middle of the night and 99% of the time I can’t sleep through the night
