My DH's experience was *not* exactly the same, so please don't make comparisons between Warfarin and Plavix. DH had 2 stents put in, in 2005. No by-pass surgery, etc, and nothing else wrong. He stayed on the Plavix until last June, when before his surgery for his broken collarbone, he had to discontinue it, and decided to not re-start. He bruised and swelled with every little bump, but, it didn't stop him. He knew that bleeding would be harder to stop. There were a couple of crashes, but he just dealt with it.
The only thing he did was stop mountain biking, and that was not really because of the Plavix. Doctors will recommend you sit on your *** and do nothing, or they will tell you to walk/swim. DH stopped doing crazy group rides/pacelining, but again, he was quite ready to give that up, not necessarily because of the medication.
