I’m not quite sure how to phrase this so please forgive me if this sounds unreasonable! Basically, it would be very much better if you didn’t use sleeping pills unless you absolutely have to. I started using them last year when my insomnia was particularly bad and it took weeks to get off them - a time I would definitely not like to repeat! I do still use them now, but only very occasionally and only when I have had a series of poor nights and really need to “catch up” with sleep. One of the reasons that it’s not a great idea to depend on sleeping pills is that the quality of sleep with them is not as good as normal sleep plus, if it’s MS fatigue that you have, then it will most likely happen no matter if you sleep through the night or not.
Insomnia is really common in MS; it’s like our brains don’t switch off properly, possibly because of damage to the bits involved in doing that. There are all sorts of tricks for dealing with insomnia (if you search for insomnia on the EL page you may find some older threads with lots of suggestions), but one of my favourites is learning NOT to look at the clock! It sounds too simple, but it really can work - possibly because it cuts out the frustration of knowing just how long you’ve been lying there, unable to get back to sleep!
The MS Trust and this website both have free, downloadable publications about fatigue - they would be worth a read to see if there are any tips that might help you.
Insomnia is bad. Fatigue is bad. The combination is a killer
I hope you can work something out to help them soon!
