Oh and one other thing Derek- you mentioned you take St. Johns Wart- be careful dog, that drug is a potent enzyme inducer... Meaning it speeds up the enzymes of metabolism (CYP450's) that break down a lot of drugs... So, for example you mentioned you have hypertension, so I assume you take something for it? It's very possible that because of your St. Johns Wart, you are going to have to take a LARGER dose of your anti-hypertensive meds to get the same effect...
I had a friend on a bunch of meds, plus st johns wart and told me " ever since i started taking St. Johns Wart, ive had to increase the doses of my other drugs because i dont think they were working..." Answer- Enzyme induction, get off the St. Johns Wart. It's junk anyway...
