Rossz,
I use the Trimix. It is under my insurance, so the cost is full the first part of the year as I deal with a high deductible, then a copay applies. My pharmacy helps a bit by packing the liquid in two vials of 5 ml rather than one of 10. This lets me use from one, and freeze the other (there is about a 6 month "shelf life" when frozen).
I also hit up any doctor I see for ED pill samples - Cialis/Levitra/Staxyn/Viagra. They do get them, it just depends on how they want to hand them out.
Also, "slim" is not "none". I try to remember that myself.
And, Welcome to HW.
