Hey, no worries dude. Noob here too(reaching 8th month in gym now), going slow and steady is also important cause you might get discouraged if you hope for too much but don't see results. Give yourself sometime to improve.

"is Optimum Nutrition's whey protein, multi-vitamin from pharmacy and kept on eating on both natural proteins and carbs good enough? i dont have a big budget."

What you're doing here is good. But you have to be honest with yourself regarding exercise matters, etc. is it intense enough? The protein supplement does help. I'm tight on budget too and go for EGGS! Yes, cause your parents won't bug you for eating eggs. Or once in a while ask them to bring you for chicken chop or steak. I do get scoldings for buying supplements ya know =P

anyway, my stats are
age: 19
height: 181cm
weight: 69kg

I started BB 7months ago, so very new to it too
just my 0.2cents

hey gurus, I've just got a bottle of creapure micronized creatine monohydrate. I realised I started sweating profusely even though I've not really went intense in comparison to last time. I noticed lower strength and my reps dropped too. Is it because the body is still adapting to it? or should I discontinue? please advice, thanks!

I see, the sweat could've been part of the water retention from the muscles ay?

As for the 5lbs protein, I use to take BSN Truemass. Lasted a long time too when i took it once a day.
But soon I realised once a day ain't enough if you lack other source of protein.
