Copaxone

Hi all I was diagnosed with RRMS in January of this year and have recently started taking Copaxone. I was just wondering if anyone on here has taken Copaxone, and if they have had any side effect. So far I have taken 3 injection, but have already experienced spacing out and worsen headache (this is under review with my MS nurse). I also tried to go back to work Monday for the first time in 2 and a half months... Sadly I wasn't even in work for 2 hours before my legs started to get pins and needles, I also went light headed and struggled to walk! I feel like I have paid for it today as I woke up this morning very tired and unable to get out of bed. I work an Office job so was sat down the whole time... Any advice on how to help with this would be appreciated. As I'm sure you can imagine only being able to work 2 hours every other day or so just isn't suitable. If anyone has any experience with Copaxone, or has had any similar experiences id really appreciate if you'd share or give advice. Feel free to message me if you don't want to make it public.
