I started Avonex 3 years ago. Like you, I had no symptoms by the time I started drugs. It is hard to feel fine, then take a shot that makes you feel poopy. I am 52 years old, still working full time, am a grandmother, and have an active life. I decided to go through with treatment so that in case MS takes its toll, I won't look back and wish I had tried treatment. Do I have side effects? Yes, still. For me, they haven't gone away. I just plan around the shot each week. As long as I can veg for a day, the rest of the week is great. My neuro prescribes Norco for managing the discomfort of side effects. Tylenol/ibuprofen wasn't kicking it. I have settled into my routine and life is still good. Different, but good. I have absolute support from my husband. He requires nothing of me on the day I inject. His support keeps me going.
For me, injecting at bedtime and "sleeping through" the worst of the side effects didn't work. Sleep was elusive. I have more success managing things by injecting in the afternoon. I am awake and able to take meds in a timely manner and avoid waking up in the middle of the night with fever. By the time I go to bed, the symptoms have peaked and I am on the downhill side. The following day, I don't plan to do much of anything but rest. Some weeks are better than others. Wish I could figure out why. It is what it is, though.
This post is not really what you asked for, but I felt like sharing my story with you. I want you to know that even with side effects, life is still great. I think many people get over any sides effects in a few months. I pray you will be one of those! If not, you will learn the best way to deal with any discomfort. As my husband often says, "Keep your eyes on the big picture." At the end of the day, we all have to make the decisions we feel best and walk on.
As an addition, many people post about hating needles and dreading the shot itself. While it is certainly not something anyone looks forward to doing, in the grand scope of life, come on! My youngest son is a Type 1 diabetic. Didn't hit him until he was 20 years old--a college student/athlete living far from home. Needles are a part of his everyday life--several times a day. I look at his courage and strength and my woes pale. What I wouldn't give to take his disease on myself. Micah is another source of my strength. Find yours--you will handle MS like a champ. What doesn't kill you makes you stronger!!
