After saying I was going to go slow, I also took 2 drops this morning. And then because I had some maca powder with vit C in it around an hour later, I took another 2 drops this afternoon.
Whilst I haven't really noticed any physical symptoms, I have been very "on edge" and have a feeling of strong pms. It seems to be affecting me more on an emotional level at this stage. Although I have been very tired today (but that could be explained through lots of other reasons).
