I am very pleased with Rocket Rx's service -- prices are competitive; online experience is quick, easy, user-friendly, and thorough; prescriptions are written quickly and delivery turnaround time is super fast. I don't like the fact that I cannot alter my prescription dosage and/or amount. I started with a daily dose of 2.5m Tadalafil and received 84 tablets with my first delivery. I spoke with a Physician about two or three weeks into it and informed him that 2.5mg daily was not enough; that I was taking 2 to 3 tablets daily (no more than 7.5mg) but I believe that 10mg every other day -- or 5mg once a.m. and once p.m. -- could be ideal; I was given 5mg once daily with 32 tablets prescribed & delivered. I was hoping to select the 2.5mg dosage once again, at 84 tablets, so I can titrate intake as needed. I'm married w/ 2 children. There is NO planning marital activities -- they just happen when & where available, and when the mood proverbially strikes! With these circumstances, at 45yrs of age, taking what I can get, when I can get it, is absolutely critical with regard to keeping spontaneity alive and well! But now, I am left guessing: When is the best time to take the limited amount of tablets I have remaining? I tried to go back to the 2.5's @ the original quantity of 84, but to no avail. Regardless, ROCKET RX is a jam-up service that offers legit generic prescriptions with a bargain pricetag. I understand the FDA's stronghold given "recommended dosages," but some folks are just different and require more... sometimes less. The pills work!!! Cannot say that enough. Stay healthy. Exercise. Eat right (somewhat). Drink plenty of water and watch blood pressure. When the Little Guy fails you, look no further than Rocket Rx to get your marriage / Adult Life back on track with (what I've found to be) quality generic prescriptions. I hope that someone finds this at least a little bit helpful and informative.
