I'm sure they will. The first couple of nights I couldn't get to sleep, but after that it was where I would get to sleep but wake up 30 minutes later followed by a night of waking up about every 5 to 10 minutes from dreams and panic attacks. After a few days of that I thought I was going nuts. I still have sleep issues but I'm able to manage them better now. I've been an insomniac for over 40 years.
For about 15 years alcohol helped me get to sleep and stay asleep, then 5 years of needing more for the same effect, then a couple of years of hitting it way too heavy as it started backfiring on me. Like needing a 1/5 just to get any sleep at all. I'm not quite 1/2 a year into this but it is way better.
