To:Marijuana Consumers?

I started smoking weed about 2weeks ago maybe 10 times in those 2weeks. Well now when I smoke I only get high for about 3hours. I remember my first time getting high was about 2 hours since I fell asleep but my second time I was high for about 6 hours. I was wondering if I stop smoking for a month or so and then smoke again will I get as high as I did the 2nd time. If not how many months would I atleast have to be sober for? Thanks. Let's just say I have permission to smoke it. Also I smoked some kush that had been out for atleast 3-4weeks and I got a major headache is it because the weed was dry and not fresh?
