I used to love coffee and drank it every day. I could drink 10 cups of coffee or 1.5 Liters of energy drink and still fall asleep when I went to bed.
Since I tapered off Finasteride and crashed with Post-Finasteride-Syndrome symptoms, my caffeine tolerance completely changed.
Now just everything more than a tea spoon of instant coffee after midday, let me stay awake for the whole night. As I found this rediculous and I couldn’t believe it was true, I made the mistake again and again and drank more than a teaspoon. F. e. yesterday I drank a quarter of a cup of thinn coffee. In the evening I was extremely tired but didn’t fall asleep for 10 hours.
I find this extremely rare. Does anyone have or had these symptoms? I am still tappering of since a year (now 60 micrograms).
Is there anyone who has a biochemical explanation for this phenomenon, other than coffeine? I mean what changed in my body that I could drink 7 cups of coffee a day and now I am limited to half a teaspoon of instant coffee powder?
@strider, do you have any idea what pathways changed?
