Been on effexor, and most of the other meds, same story. 'bout two to three months, then useless.
I had a small prescription for Abilify over 10 yrs ago or so. It worked great for me, loved it. Can't remember what it was prescribed for, or why it was stopped. It was before PTSD and it's friends struck full force.
Doc won't give me Abilify or other sleep aid because I'm on clonazepam or something like that (cousin of valium). He's afraid they will have a synergistic effect instead of an additive effect. He told me to just take the clonazepam for a sleep aid. I really don't like that idea because I have a phobia of becoming addicted to medication. I'm trying to take the clonazepam as little as possible unless I'm just exhausted from fighting anxiety and need a short vacation from it. I also do take it if I am in danger of having a panic attack, or I'm going to a place or event that I know I will or probably will have difficulty with.
If it comes down to it, and I NEED to sleep, I'll take it. Chronic sleep deprivation... well, I'm sure most of us have been there at one point or another.
As far as being a fast metabolizer or the other. Mentally they do their thing for a few months then lose effectiveness. About the only thing that continues on as long as I'm on the med is sexual dysfunction or impediment. My body adjusts partially to it, but not completely. When I start the med, it's a no go. Then after a few weeks I can get the job done, but it takes forever and I have to be so... enthusiastic I risk injury (been over 6 yrs since wife helped, so it's a solo thing). Forever might sound like a good thing, but every time? It gets old. I just want the job done sometimes, 'Ya know what I mean? :cool:
Edit:
I'm on Busiprone (for generalized anxiety disorder)
Divalproex (Mood stabilizer)
Prozosin (Anxiety, PTSD, and panic disorder)
Amitriptyline (lots of stuff, major depressive disorder, anxiety, ADHD, bipolar. The last two I'm not full blown, but have traits thereof).
Recently taken off of Pristiq the last SNRI that failed. Doc is taking a "wait and see" how these meds do because, like I said, most if not all of the SRI, SSRI, and SNRI have been tried on me.
