I voted did nothing. Although what it did do: made me hyper, unable to sleep, ravenous and never satisfied no matter what or how much I ate. Oh and weight gain. After the side effects resolved, I was still experiencing symptoms.
I do it because I'm just hopeful. As I last resort, I just want relief. I should say my sx are mostly sensory and never resolve completely. The only relief I get is that the side effects are so intense and overwhelming, that I forget about the MS symptoms for a couple weeks.
I always say, I'll never do that again, but when feeling so crummy I give in to the doctor.
