How groggy does it make one in the morning?
It can be a problem. Maybe many take too much as well. It was said, at least in the past, a low dose made you tired whereas a high dose made you energetic as then other neuotransmitters like adrenaline became involved. Early today I took a whole 45mg tab because I couldn't dleep at night and was planning on training but woke up at 21.30 PM and felt like I could have slept til morning. Only way to know is by trying, like I said even 7.5mg can work though the lowest dose tablet here is a 15mg unscored one. You might also take it several hours before sleep so it hopefully washes out more by morning. It's good because it's not addictive per se and not dangerous, might perk up your mood and every doc will write an Rx for it, unlike the z-drugs or benzos.
Regarding the quatipine that dalnet mentioned, I had it once maybe 25 years ago and can't remember how it worked. There were some serious potential sides plus my impression has been that people on these dopamine blockers/antipsychotics turn into fat zombies. For situational use I doubt this is a worry though.
Z-drugs can be great for falling asleep, but they leave so fast it might wake you up due to mini-withdrawals lol. The short action is why they aren't AS addictive as long acting benzos but may again worsen your mood during the day as you go through that mini-withdrawal and sympathetic rebound. So for me, if I had a very debilitating situation where I absolutely needed to sleep I would take a Valium, mirtazapine a couple of hours before sleep and then a z-drug at bedtime. The z-drugs start working within minutes, in fact it's recommended they be taken when you are already in bed and turned off your phone and laptop, otherwise you might perk up and enjoy the high while sending stupid texts to friends, or even decide to go for take-out food with your car, as happened to me lol. Woke up and had unopened food boxes on my kitchen table and no memory of having done so lol.
