GNC Sleep Formula, plus Melatonin...side effects?

So, I'm on vacation right now and only just I have been have a really hard time sleeping, and I wasnt sure why, so 2 days ago I went to a GNC store here where on earth i'm vacationing and they gave me a sleep formula with valerian extract, zeal flower, bluerberry fruit, and some other things, plus melatonin, she said that it should work however, the day after i took it i felt sick adjectives day (even though i did sleep better) and then finally end night i got sick(throwing up) twice..i be wondering if it could be from these sleep aids beause id like to thieve them again, but im scared to get sick again


so should i completely stop adjectives use? or just take the melatonin and not the mixed one, support asap!
