I have a question regarding the different doses of Cialis. I was once given a 20mg Cialis pill by a friend and broke it in half. So I took around 10mg dosage. I cannot afford Cialis through my insurance so I was going to try the free sample voucher on their website. They have 2 different options. the every day dosage of 5mg or the 20mg dosage for one time use. I don't have an all the time problem, so I would be taking it on occasion. The thing is you only get 3 pills of one time use and 30 5mg pills. Are they the exact same thing? Couldn't I just get the 5mg and take 2 to get 10mg? That would make it so I had 15 doses instead of 6. Or is there something different about the pills? Thank you.
