Welcome to the board, Jay!

I've used Vidalista 40 mg from edpillsforever.com for a while now. To answer your questions:

1. Timing: Give it at least an hour. It’s not a race, and since it lasts so long, taking it a bit earlier actually works better for me.

2. Duration: Definitely legit. You don’t have an "active" situation for 36 hours (thank god), but the ability to perform is there whenever you're actually aroused.

3. The "Hydration" Trick: You hit the nail on the head. Drink plenty of water. Tadalafil can stay in the system for a long time, so if you're dehydrated, you’ll definitely feel that slight "head pressure" the next morning.
