Hello Bobby,
   I did not get caverjet.  I got prostaglandin.  You put it in a diabetic
needle, and push it in 1/2"  about a 45o angle to the top...
The first time they used 50mgs or whatever is written on the little needle
vial..
Limpy........
2nd Day The Dr. let me do it, and we used 70 mgs......Stiffy, round and more
than plump/

At home I had differing reactions.   At night was a real problem.  Using 70
mgs...I would have a burning hardon for 3 to 4 hours, and would have to get
up out of bed at 1 or 2 a.m. and run downstairs and try to massage the
medicine out of the swollen unit...

I finally figure out that in the morning at say 6:00 a.m. I could use the
medicine........Get an erection......have sex, and then get up, and sorta
walki it off.
To me this was the best.
A.M.  walk off the meds after.
I know the feeling.....Like a big sausage that hurts, and is plumper than
normal...yeow....it was nasty.

So, in brief......Use the meds as for me best before waking up in the
morning.
Then you can stuff mister stuffy, down your pants and walk it off.
You have to realize this was many years ago, and I do get natural erections
now, and viagra works....
I contribute that to using the injection........In other words, keep trying,
try different times of day.
Try prostaglandin....

It all helps with nerve recovery........
I am 55 now, and had RP when I was 49
I can get a hot dog! with about 33 mgs of viagra......

Good wishes my friend, and never give in...
John Loomis

I used Caverject with mixed results, but no pain.
