I forgot to add that I take out of the fridge 5 days at a time for my shots. Put it in the handy dandy bag they gave me for the AI. I found the 24 hour warm up period to be less painful than than the one hour prior to injection, at least for me.

I've had one really bad experience with dull needles. Luckily it was my arm. The needle was so dull it wouldn't penetrate the skin even with the AI. I had to keep the injector against my arm and head for someplace I could release it without the Copax going all over the room. Then scrub the med off my arm so it wouldn't burn the skin.

I'm with the others of doing a wide wipe down with the alcohol pad and letting it dry.
