First post here ever, I've been reading you since quite a bit of time. I've always been an amateur of pu'er blended tea. I've drank quite a lot of Blood Orange Pu'erh from DavidsTea in the last year without any ill effect. During the chrismas vacation I decided to try out real pu from bricks. I've got a nice teashop that's specialized in pu so I said why not.
So I get one Sho and one Sheng < okay, now I have 3 of them each but that another topic

So, basically, what are the effect on the body of pu? I've been feeling kind of bizare since I started drinking it. I've been using ~5-7g in a 180ml Yixing. I was doing a flash rinse and then 30s, 25s, 30s, 40s, 1m... The effect were ranging from weird bowel located abdominal pain to feeling weird after eating lunch ( I usually drink tea in the morning after breakfest ). I can't say I did any acid reflux. I've got this bad feeling that I'm trying to associate stuff that isn't pu' related...
This morning I tried to rinse one Sho I had for 1 min insead of a flash rinse. So far I have no ill effect what so ever ( after 4 cup of 4-5oz ). Could it be possible that I wasn't rinsing the tea enough ? Any tips, I know that young sheng are suposed to be harder on the stomach but young sho and aged sheng shouldn't be a problem.
I hope to be able to pass through this... pu is awesome, I really really like the earthy flavor it has.
TL'DR: What are the side effect do you experience when drinking Sho or Sheng Pu?
