Very nervous about taking these - there is a risk here, everyone should know that. So far, so good, it's worked 3 times in a row for me, noticed it works best WITHOUT alcohol and on an empty stomach kicks in faster. Restored my confidence in sexual matters, I feel I can go on and on once I'm hard, and can be back in minutes for seconds. Or thirds! Effect lasts about 24 hours. Side effects for me are headaches - seems to start about 6-8 hours after taking, and wears of after a few hours, bright light doesn't seem to affect me. As I said, there doesn't seem to be much research on the short and long term side affects so taking it IS a risk,better to speak to your GP as advised on the packet, but I'm being a hypocrite as I didn't! To sum up, amazing effect, the headaches I can live with, wouldn't use continously, only for "special occasions"!! 8-)
