I had saved an old post from somewhere that mentioned licorice and l-dhea. So I bought and experimented now with licorice for a month.
Unfortunately I didn't notice any effect from licorice. Once, when I had stopped licorice for a while already, I was having a pois episode. It was towards the end i.e. when I was pretty much recovering, I woke up with 7 hours of sleep, I woke up before my alarm clock but I could soon i.e. after an hour or two tell that something was off. I felt so tired, it was as if I had not slept at all. But I managed to come home and get 20 mins to lay down with closed eyes. Afterwards, I decided for some reason to take licorice again. I drank black tea and an hour or two later coffee. Towards the evening, I noticed strangely that something changed with my energy levels. Although I was a little tired, I became functioning again. There was an increase in energy definitely. It was strange as I expected that the longer the day gets the more tired I would be (as usual).
Besides the short rest and coffee, I suspect it was the licorice that played a big role. Also bearing in mind, as I said before, I was already almost out of pois. Still, I guess licorice might be good to have in those situations. Maybe I didn't waste my money buying this. I guess it's better to take in the later stages of a pois episode?
