I am going on a big trip in less then 2 weeks and have an exacerbation of my MS. The fatigue is my biggest concern. I am retrying Modafinil but had little help from it in the past. my doc is suggesting Amantidine but it seems to similar. I am wanting something short term just to give me energy for the 2 weeks we are away. I thought a short trial of Ritalin or concerta might help. Any thoughts on what to try in the next week and then use it only while I am away?
