I stand after I inject because that seems to make the drugs work faster. And if I lay down, I do lose part of the erection but if I stand back up and walk around, it comes back. It all seems to be related to blood flow. When you are standing, the blood gets to your responsive areas easier. quicker, etc.
Just recently, I found that the closer you are to the expiration date of the Trimix, the less effect you will obtain. It definitely doesn't seem to last over 90 days.
