hahaa thanks for the info - interesting!
I don't think i'll go for the Cialis despite needing a serious libido boost!...can't remember what i was reading at the time but this article cited all these 'hard-on' meds as being culprits of something nasty heart-wise longterm.
The niacin...i've tried that and it makes one helluva flush - especially 1g! Jeesh!
It's a methyl sponge tho' so it's not good for my undermethylated state. I do like the flush however :-)
