Helloo.

Does "uyku haplari" or something like that means; "sleeping pills" ? 

Thanks

Technically correct. But we just call it in singular form " Uyku hapı "

so in english it would be "sleeping pill" eh i got it tesekkur ederim

i ask a lot sorry for bothering ama if i want to say "my sleeping pills" do i add ´-im´ or should i say benim uyku hapi?  

No problem trister..[ btw I wish you had a shorter name as when to adress you i feel bit lazy to write the whole name]

Yes, you should add 1.st singular marking [ in this case "ım"]

[Benim] Uyku hapım [you dont have to say "benim"]

You can make it plural too.

[Benim] Uyku haplarım

its too late to change my username if there was a way to change it i´d do. to make it easier for you guys haha

i see. i got it. what if i just say uyku haplarim without benim, would it still be right?

Of course it would still be correct without the ´benim´.

(Benim) uyku haplarım

Whenever you see something in brackets, eg (benim), it means the part in brackets is optional. 

i got it. thanks!
