questions about vardenafil (first-hand experiences only)

[Implant_Curious]

I have tried sildenafil (50-100mg) and tadalafil (currently on 5mg daily). Sildenafil seems more potent, and am considering going down to 2.5mg tadalafil daily and adding sildenafil on top of that. However, I also want to try vardenafil next. I was wondering from those who have experienced it (first-hand experiences only please):

1) how does its efficacy compare to sildenafil? Is 10mg vardenafil equivalent to 50mg sildenafil?
2) is food less likely to affect its potency compared to sildenafil?
3) does it affect latency/how long you last? sildenafil seems to also make me last longer, but not tadalafil. I have read vardenafil makes you last longer compared to other PDE5i
4) how long does it take to start working compared to sildenafil?
5) how long does it last?

I tried vardenafil only once and it didn't work because I took it in combination with cabergoline. The erection was mediocre and I did not feel aroused.

so you can't really comment because you took it with cabergoline at the same time...
