Welcome to HCM
You are a shift night worker and problem of sleep or insomnia
is very common problem in night shift workers. Its good that you stopped to take corez. Zolfresh is a good hypnotic
drug and it helps to induce sleep. It is also non addicting and have very few side effects. It is a good drug to take but don't take it for long time as risk of rebound insomnia is there with this drug.
Other options are also there like Ramelteon
etc. These tend to correct sleep cycle
by altering brain centers for sleep and these are also non addicting
