What are some ways to cope with insomnia from quitting smoking, aside from taking sleep aids?

I’m heading into day three of giving up nicotine. The biggest issue that I’m having is the restlessness. I can’t sleep, I think I’ve slept two or three hours in the last two days.

I’m having trouble both falling asleep and staying asleep, even when I do nod off I feel like I am not “actually” asleep. Not sure how else to describe it.

I have a history of insomnia and sleep disturbances, so I don’t want to rely on sleep aids, but I have read and also heard from others that this sleeplessness and excess energy can last for weeks. I have never tried to quit smoking before, certainly not cold turkey, so I really don’t know what to expect as far as that sort of thing goes.

If you, or someone you know, had this issue when giving up cigarettes, what worked? Should I just ride it out? I don’t feel tired, but I do feel like I am not getting anything close to restorative sleep.

Thanks.
