Hi Dejibo,
When I was on "C" I always shot-up at night, after my shower. I didn't want to shower/bathe with an open wound/needle hole. Germs can enter. Also I thought the shot site would be fine by morning and not have issues with it all day at work.

Maybe trying it in the morning is a good idea like Frank and legzzalot suggested. It should be well into your system by then and maybe no trouble with sleep or staying asleep. Worth a try, IMO.

Is Insomnia on the "C" list of side effects? I don't remember. I always checked in the box for their insert paper. On the bottom right, it shows the latest printing date.

You can look if it's an updated insert. There maybe some changes or updates. I always kept them in a file for comparison. I hope you get some good, sound sleep.

Waking up all the time or fitful sleeping is not restorative sleep. Good luck

Yes, Desinie I am a Night Owl. Some people are Loons (birds that are up before the sun). I wish I could change it, but I sleep according to what my body demands.
