Sometimes, hours after i get high, I always have this strange 'pressure' feeling in my head that gets uncomfortable. Also my eyes feel weird and they water. But mainly its a feeling just behind my eyes, i cant really explain it but its just a tense feeling.
My question is, does anybody else get this and wats the explanation
EDIT: id also like to note that this feeling will last the whole day/nite after i smoke. And sometimes i feel it even if i dont smoke.
