Totally agree it's a personal choice for each person. When the med becomes that bad - totally agree with dropping it.

Hope whatever you do next works out for ya.

There are some days I wish I wasn't the human pin cushion

, but until copax - I was having back to back flares. Still not sure if it's the med or just the way my MS would've gone, but will keep poking away. If the copax ever stops working, not sure if I'd do any of the stronger meds with all my wonky reactions to meds.
Hang in there!
