I get a very quick tolerance buildup to GD. Went camping last week with a fresh bottle got wasted first night, took 3x next night got very stoned but lacked the spiritual experience outlined by Master Wu, 3rd night inhaled rest of bottle got a strong body stone but was very disappointed.
Moral of story-use sparingly.
While I enjoy the occasional spiritual dose I usually just take about 1/3-1/2 an eyedropper full then supplement it with smoking about 1-1.5hrs later.
