Numb fingers

Well... last week i take a 4 days break (the most time i stayed without smoke in more than 1 year). Strangely, it was very bearable, i didnt felt any need to smoke... due to the knowledge of how to keep the mind empty, i could stay chill without the weed.

Anyway, after this break, i smoked a nice j of a very good weed, with a friend of mine, and become absolutely and completly stoned. It was amazing, even somewhat scary. I dont know how i managed to walk to his house, cause i was literally out of my mind.

When i was stoned, and the day after, seemed there is some 'tracers' in the tact. Like... when you have 'tracers' in the vision, and you see, for example, a bird flying, you see a curve with shows the places where the bird passed before. Well... i feel like a 'tracer' with the tact. Like, if i touch a hot thing, there is a small delay since i touch the thing until i feel the hotness of it. And when i stop touching it, there is a great delay until i stop to feel the hotness.

Or, if i put my finger on my arm, next to the wrist, and go moving the finger to the elbow. Then when my finger were in the middle of the arm, i would still feel my finger in the wrist, and the same time in the middle of the arm, (and in all the places between them). Then the feeling the finger was in the wrist would fade slowly, and when it reached my elbow i would feel the finger was still in the middle of the arm, and at the same time in the elbow (and again in all places between them). When i stopped the finger in the elbow, it would take some instants (maybe 1 second) until the feeling my finger was in the middle of the arm fade, and i feel it was only in the elbow.
Very strange... i remember i felt like this only during my first times.

And until today (3 days after), im feeling the tips of my fingers numb. Not exactly numb, but seems they are over sensitive. I grabbed the things and they would fall, because i was grabbing too weakly (but feeling as if i were grabbing normaly). For the things dont fall, i had to grab them strongly (or rather i felt i was grabbing stongly).

The first time i smoked, i keep feeling this numbness some 4-5 days after i smoke.
Anybody else felt like this sometime? If so, do you know how to stop it? Cause im becoming very annoyed with this numbness in my fingers...
