Well the last two injections were super successful!! I did them before bed, and took a Naproxen (Aleve) an hour before (lasts longer than Tylenol/Advil). I didn't wake up at all or have any symptoms that I know of. Granted I was only taking 0.25mLs... I go up to 0.5mL tonight so that might change things up a bit. I have to make my way up to the whole vial which is over 1mL so I imagine the symptoms will come back as the dosages increase.
