This correlates somewhat with the recent thread I started about the "Fentanyl" powder. It seems that since using this, it has given me headaches, both at the front my of head (forehead are) and at the back of my head (right around where my head and neck meet).
Is this common? I've not experienced it before, as best I can remember. Is there any particular opiate that this is associated with?
