in the name of Allah

I've started working just yesterday ... it's not fun at all!!
I wonder if only me feels so tired and sleepy during the work time .. I wish these feelings last soon.
My Boss is very generous, he gave me a separate office, but I feel that this might be the reason I feel sleepy all the time ... there is no noise at all around me!!
Any advices to eliminate these feelings are strongly welcomed ... hahaha

Wish all of you a nice day
