I know it was important because I tied this knot. I always tie a knot when I need to remind myself to remember something. I know it has something to do with generic viagra but it’s not the obvious - that there is no difference between the generic and the branded viagra. They are bioequivalent. Everyone knows that. Even though the generic sometimes comes as a slightly different shade of blue (or not even blue at all), all pills for the treatment of erectile dysfunction supplied through reputable online pharmacies have the same effect. Wait, it’s starting to come back to me now. There is a difference. When you buy the branded tablet from your local drugstore, you are guaranteed to get the written set of directions approved by the FDA. When you buy through the internet, there may be instructions, but they need not contain all the information required by the FDA. Right. We’re on a roll now. Those wonderful scientist types working at the FDA have been getting all worried about Transient Global Amnesia (TGA). Now, here’s the thing. A tiny percentage of people who take viagra find they can’t remember everything that happens in the hours following. So you might take the tablet in the restaurant and wake up the next morning not being able to remember the drive home (or anything else for that matter). This could be dangerous to your health if you can’t remember what you said to your partner at a critical moment during the evening (or how your car came to have that bent fender). So, the next time you read all the small print in those helpful instructions (something you do all the time when you have nothing better to do), you’re going to see a new warning about TGA. It’s going to be very reassuring and the FDA will be right. Only a very small number of people who take viagra, whether branded or generic, will experience this forgetfulness. And quite what you’re supposed to remember to do when you find yourself forgetting is unclear. But, assuming you remember you forgot something, it’s called TGA and it’s nothing to worry about. Just remember to take a lower dosage tablet next time and all will be fine.
