I've heard of pain, had some stinging sensations myself. Never read of anyone going numb down there. You should have probably started at 1000mg a day to allow your body to get accustomed to PM.
If I were you, I'd drop the dose to that for a week or so and see if the numbness subsides. It's not like a higher dosage is going to speed things up necessarily, anyway.
If things get back to normal after that week bump it up to 1500 for a week then to 2000. Just my opinion though.....
Now that that's outta the way, I'm curious. How can it be "very" numb? Something's either numb or it isn't. Not to mention, it's very numb in the thread title, but only "kinda" numb in the OP. Did it improve?
Also, why is the willy in "little willy" capitalized? Did you name it that?
LOL ;p
