Hi Heather- Welcome to our site- you'll find a very supportive community here. Are you experiencing pain at the injection site? I've found that doing manual injections rather than using the Rebiject seems to help a lot. Reason being, you have much more control of how fast the medication goes in. If you're not squeamish about needles, it's worth a try. Where you inject also makes a huge difference. You have to watch for veins and capillary beds, which can hurt like hell if you hit them. I've eliminated my thighs from my injection schedule, as I have a lot of surface veins and was always getting bruised. I also take 400-600 mg of Ibuprofen prior to injecting.
Depending on your work schedule, you might also consider an earlier injection. I do mine mid-afternoon now and I find I have fewer if any of the dreaded flu-like symptoms. I was having problems sleeping with night sweats and feeling lethargic the next day when I did them at night. An MS Lifelines nurse told me that your metabolism slows down at night and since most of us can't drink a lot of water before bedtime (read: up all night in the bathroom!), it's harder to stay hydrated. Hope this helps!
