OK so I tried brompheniramine tonight, so far I am liking it alot. I used 8mg and haven't felt too itchy yet, it is less sedating than say doxylamine but it seems to have a bit of a mood lift, maybe thats just the xanax but I think I could tell. It has SNRI properties so maybe thats why.
The really awesome thing is dosing 20ml equates to 8mg brom and 40mg DXM, that makes up 2/3 of the dose I use to potentiate, so it works out rather cost effective. I will do a write up on it in the original post tommorrow.
