Multiple Sclerosis - New Drugs

I am very excited for the first time in a long time. Multiple Sclerosis does not seem so scary today (I mean literally today - as it is scary everyday)! I just talked with my doctor about participating in a test of an oral drug for multiple sclerosis. I am very excited as I have the most difficult time with actually giving myself the shot of Rebif three times a week. I love Rebif but the shot trauma is just too much for me. However, I must take the disease modifying drugs as there is nothing else for multiple sclerosis.

I have two concerns with this test and all tests as there are downsides:
1) I need to be off of Rebif for three months prior to participating in the test.
2) I must do monthly spinal taps.

I don't usually do too well with spinal taps because I get the bad headache which just makes the multiple sclerosis worse for a few days. However, I have consulted with my doctor as well as the research personnel and they both assure me that this spinal tap utilizes a different type of needle that makes the headaches less likely.

I am very concerned with being off of Rebif for three months as if for some reason something does not work with the test I will have nothing fighting my multiple sclerosis for three months. That is scary. However, I am so excited at the prospect of doing something to forward research for multiple sclerosis that I will pretty much do anything.
