Now, solve this: Review: I noticed I was very tired and headachy after taking Vitex, but I read that is a common side effect and that it was temporary. After the first week, I only noticed the tiredness increasing. I would feel almost confused at times and just plain strange. When taking it during the day, one time, I completely drove past the shopping center I was going to. I'd go through these spells where I felt very heady, like I was going to pass out. I was only taking 250mg per day. I had high hopes for this as a treatment for PCOS, but I couldn't continue with it. This doesn't seem like a common result, but malaise and confusion are listed among vitex's side effects. Maybe I should have tried vitex fruit which is less potent than vitex extract, but this is something I'm not messing around with any more! Back to progesterone cream!
