Effects - Pains?

[bob2k8]

Swim first started to take GBL about eight weeks ago and took it every day for about two weeks, and he noticed that his kidneys started to hurt (quite a similar pain to stanzonol), so he decided to convert his GBL to NaGHB using the well known method form this forum. When he started to take the course of GHB the pains went away, but over the last week or so the pains have started back? the Ph is nutral? Swim is confused?

Swim has been taking a lot the last two weeks (it was supposed to used for training) but he has gone from using it just after training to using it 24/7. it's also effected his sleeping patterns too, He spoke to his mate, who has been taking GHB for about five years, and he said that no matter how much and how long a person takes it Swim should not be getting any pains.

Could a Swim please advise a Swim. Has the abuse of GHB resulted in the pains?
