FeelingLost - That's my experience too. I much prefer the feeling at 19 vs 45 without the AI (I've felt them both over the years). You're at .125 mg every other day, which is 1/8th mg every other day. A low dose AI has made all the difference for me. I always caution guys that this is a powerful drug, and it's easy to take to much if you're not careful.
