Here is what I can tell you about Prami from my experience (in no particular order):
Work your way up for the dose.
Always take it with food. If you don't it tricks your brain into thinking you are going to vomit. You won't actually vomit, but you will feel like you are going to and you get dry heaves. Pretty weird feeling.
Can cause sleep issues. It does put you to sleep. But then you sometimes wake up a few hours later WIDE awake. And sometimes you keep waking up every hour or two all night. This seems to lessen over time to some degree.
It seems to increase saliva. You will sometimes feel like you are drooling because there is so much saliva in your mouth. You often wake up with drool on your pillow.
It takes FOREVER to have an orgasm on this stuff. Like an hour sometimes. This is a pro and con. The lady in your life may enjoy it the first time or two. When you are on cycle though and want nookie 4 times a day this can be problematic. Throw in the sweating from deca/tren and things are even worse.
If you get your prolactin low enough you can bounce right for round #2.
You can feel happier on prami due to the extra dopamine floating around.
Some people become obsessive or addicted to things like gambling or sex. Can make you more compulsive too.
Taper off it when you are done.
So as you can see, there are good and bad things about prami. You will experience some of them. It is great protection if your E2 gets elevated. And some of the bad things about prami seem to lessen over time. Again, this is my experience. Yours may be different.
