You have been experiencing the anxiety attacks that are called panic attacks. Symptoms usually increased to peak within 10 minutes and subside within next 10 minutes. You need to calm yourself by doing breathing exercises and relaxation techniques.

Apart from these for instant relief you can also take drugs like mouth dissolving preparation of clonazepam. You are taking plain preparation of clonazepam.I usually give mouth dissolving preparation as as and when required basis to my patients in addition to the oral dose of clonazepam.

Xanax is a alprazolam which a similar drug to clonazepam but has short half life and high potency, So this might be the reason why you have been relieved from anxiety symptoms rapidly. Xanax has high habit forming potential as compared to clonazepam, because of the short half life. You can ask for switch between two drugs, to your prescribing psychiatrist.

Shift workers are always having problem with sleep. So other symptoms of fatigue, lethargy, depression are all somehow related to it. For maintaining your sleep wake cycle, you need to take drugs according to your possible sleeping time. You can also go for melatonin increasing drugs as per advise from your psychiatrist.
