PIO- Needles?

Has anyone seen this youtube clip where this girl uses a 25g needle instead of a 22g to do her PIO shot?   She has me convinced that it's fine to use a smaller needle!  It's sad that I'm worried about those shots and I haven't started stims yet!  

Anyone who had the Bravelle/Menopur protocol, what size needle(s) did you use for the injection?  Did you always use your abdomen for an injection site?  Did ice help with any stinging?  Anything else I should know?     

Sorry that this is TMI but Lupron is really interfering with regular-ness in the bathroom.  It's just not happening!  I guess I should be thankful that I'm not having headaches or hot flashes, right?!?  Arrgghhh!
  

Injection #1=Lupron sucks already!

Omg.  The follistim pen was a piece of cake compared to Lupron.  First injection this morning and it didn't go so well.  I took the syringe out before turning it over and medicine sprayed out.  Stress.  Last night, I found conflicting  instructions- one said to do 20 units and another said 10 units.  I did 20 units this morning and have placed a call to the nurse to get this worked out.  More stress.  I kept seeing air bubbles and PC reminded me how dangerous those were.  He was really sweet and trying to be helpful but... add it to the stress!  That stuff really stings!  Major stress!  And I lay here typing this instead of getting ready for work because all that stress was followed by throwing up and almost passing out.  I keep asking PC what went wrong... he said I didn't do anything wrong as far as the injection but I let the stress get the best of me.

I know... suck it up... there's a lot more to come!  I'm amazed at all of the strong, amazing women who have gone through this more than once.  I understand why but after one little injection I am just amazed.  Can you please tell this wimp how to avoid a scenario like this every morning?
