Yea I couldnt agree with Negrogesic more, on all the points he made.
If you truly are certain that you are deficient in NE, then Strattera would probably be the best medication to take since it specifically inhibits the reuptake of NE.
You may also want to try some of the tricyclic anti-depressants, since many of these will also increase NE levels, but are not so specific to NE (meaning you will also raise your serotonin levels).
I also agree with Negrogesic that increased NE levels will likely make you feel very on edge and jittery.
It would help if you could explain why you are so certain that you are deficient in NE. You only tell us that you are certain, but dont tell us why you are so certain, which is why so many people are suggesting you go to a doctor. People self-diagnose all the time, and are often completely wrong in their diagnosis. Perhaps you have reason to strongly believe you are deficient in NE, but until you tell us why you are certain, you must understand that people will be doubtful, and suggest you speak with a doctor.
By the way, do you have low blood pressure. For those who are NE deficient, you would expect them to have lower blood-pressure. However, this does NOT mean that low blood pressure equals low NE levels, it is just one indicator.
Getting back to things that you could take that might increase NE levels (assuming you actually do have low levels).
You could also consider Resperine. This will also increase NE levels, but through a different mechanism (it is a more complex mechanism then reuptake inhibition, and has to do with vesicular transport), but once again, this is something you would NEED to discuss with your doctor. There are also alpha blockers like phenoxybenzamine, which would also increase NE levels. I know you seem intent on treating this yourself, but even if you are 100% correct that you have low NE levels, you would still need to work with a doctor in order to safely and effectively, come up with a drug regimen to increase these levels.
If you want to try some things without the supervision of a doctor, that you can safely do, and might increase NE levels, I suggest the following.
Increase your protein intake (meat, eggs, etc). Protein is used by the body to make l-tyrosine, which is then eventually converted to NE (from dopamine).
You can also try to take l-tyrosine supplements. You mentioned you did this and it worked for 2 days (Im not sure how you can really know how long it increased your NE levels, other then how you "felt", which is HIGHLY subjective). So I would suggest taking l-tyrosine again, for at least a month, and see if you notice any difference.
And oddly enough, I just googled things which can increase NE, and believe it or not, banana PEELS contain high levels of both NE and dopamine (no guys, this isnt another "smoking banana peels" joke).
So, in summary, if you want to try to raise levels on your own, you can
1-eat more protein
2-take l-tyrosine for at least a month
3-.....I guess scrape the inside of a banana peel and eat it.
Other then that, there are many, many different meds that can raise NE levels. Some things (like Strattera) will selectively raise NE, other things will raise NE, but also raise serotonin and others in the process.
So, if you want to try these medication, talk to your doc about
1 Strattera
2 Resperine (alters vesicular transport)
3 Alpha blockers like phenoxybenzamine
4 Tricyclic antidepressants
That should be plenty to give you a good start. I would think Strattera would be the best med to try, as it is one of the few things that really targets NE, specifically. Hope this helps-DG
