I've posted this often, but just a reminder that Cialis does a "first month free" offer.
Go to their website, print the form (there may be a copy in the sample box), and take it with the prescription. My (big store chain) pharmacy had no issues at all processing it. There is no obligation to keep refilling it.
I did that with the 5mg tablet, and got the free month. My Ins. only allows 8 tablets a month (regardless of strength) for ED meds, so I then got another prescription for the 20mg, and cut those in quarters as best I can with a pill cutter. The uro docs know all this too well - mine had no trouble writing another prescription.
At $160 a month for this stuff, take all you can get for free.
No, I don't use ADC - there are potential legal issues that don't work for me. If you are retired, you might investigate them - prices are a bit more reasonable.
