Does viagra casue fatigue the next day?

I recently realized I experience serious fatigue the day after taking viagra, with or without sexual activity. I had noticed the fatigue in the past but had not made the connection until lately. Although it’s a small price to pay, I have to give some thought into the nights I plan on taking it, knowing the fatigue I will likely have on the following day.

I am often very tired the next day after taking Viagra. It is not because of the physical activity. It's because of the Viagra.

I thought it may be due to excess sexual activity but I don't think so now. They were times where there was no sexual activity and even if there were sexual activity I didn't feel unusual the next day. But when taking it on a daily basis for a week I did feel extra weak. I would sleep 10 hours, get up for a few hours, and go right back to sleep for another 8 hours as if in the Twilight Zone. No there is something there and it's not due to sexual activity. It took me a while to suspect it was the Viagra.

I also feel fatigued the next day after taking Viagra with or without sexual activity. With regards to blood pressure I think my blood pressure goes down after taking Viagra. I once went to the doctor after taking Viagra and my blood pressure was normal when at other times it is higher.

My fiance states that yes, it certainly does, due to the rise in blood pressure and heart rate. He also states that you should be sure you have no type of heart condition before taking this and that your blood pressure is under control, as viagra can easily lead to serious problems to people who were unaware they had issues before due to the way it works.
Fatigue is common, but it would depend on how severe the fatigue is. Remeber, sexual activity can make you tired, and if you are having sex 4-5 times in 24 hours, you are going to be worn out. So always remember to add that in. Concider the facts, weigh the effects, then decide if you should be worried.

The fatigue , my friend comes from all the sexual activity you had the night or day before... it is not the viagra. You are physically tired or fatigued or exhausted from the sexual activity.

Now fainting is a side effect (serious) from viagra... but you did not faint... with all due respect, you had a great time.

Take care and be carefull
