Modafinil works really well for me (300/400mg keeping me awake and FOCUSED but not buzzing/twitchy) but worked poorly for my brother (no noticeable effect at similar dosage).
Since taking noopept I have noticed more of a willingness and now desire to learn, something which was an issue in my past. It also seems to help me work for prolonged periods of time without getting burnt out. (anecdotal, could well be placebo effect but it works for me!) Feel free to ask me anything.
For particularly taxing times, I have a bottle of oxiracetam that I use in conjunction with the piracetam. It reminds me of the heightened focus I used to get when I had prescriptions for Ritalin/Adderall growing up, yet without all of the nasty side effects. It was great a couple of hours before an exam during my masters program, or in the mornings right after my daughter was born.
I tried pramiracetam once. I got nothing but a bad headache from that.
I have a few samples of noopept around somewhere, but I don't think I've been brave enough to try them yet after the pramiracetam disaster.
Oh, and I've recently added 200mg of huperzine A to my morning regimen. Not sure how much it helps. Seems to be a decent replacement on the weekends when I don't want to take the full cocktail.
I stopped taking that because obtaining it OTC where I live is kind of hit and miss. The drug requires a prescription (generally to treat degenerative conditions common in the elderly) and some pharmacists are more hardline in that respect.
In hindsight, given it's a relatively recent compound and there's so little research on it, I guess it's for the best. I wonder if my "experiments" can have a negative impact in my health, especially my mental health; I hope the estimates regarding the safety of piracetam turn out to be correct.
Piracetam is actually well-researched [1], it's been out since the early seventies. It's the most researched of all of the nootropics, AFAIK. I'm unaware of any studies that resulted in health damage from piracetam, but would, of course, love to read any if there are.
[1] Take, for one example: http://www.ncbi.nlm.nih.gov/pubmed/?term=piracetam[Title]
I used to take a much larger, and more structured regimen, and found it very difficult to keep everything balanced, some things increased the consumption of ACH so much that I had to start taking choline supplements, but if I screwed up my timing/doses, I'd hit nasty lows from too much choline intake. I gave up on it, as the only noticeable difference I had from the regimen was a more difficult job of timing, having to have a lot of pills around, etc.
I stick with nootropil due to its well-established safety, and minimal impact on overall chemical balance.
If you are diagnosed by a doctor with a hypoxia-related condition, I would presume you are self-treating with piracetam, because I don't think it would have a great positive impact, unless your condition would be quite severe.
I suggest looking into pentoxifylline (http://en.wikipedia.org/wiki/Pentoxifylline) and then re-evaluating your situation with a doctor and whether it would be ok for you to try it. I think you'd see more results with it rather than racetams, maybe except for levetiracetam, which would also require a prescription.
Also, pentoxifylline should probably be almost as cheap as generic piracetam; levetiracetam, even generic, is not however.
Do not take any of these Rx meds on your own, without consulting with a professional.
I know people generally hate going to the doctor, but in some cases they do help :) Think about all the advantages taking only 1 pill for your condition could have, instead of a whole stack, not to mention the financial savings.
I'm not keen on other drugs, as piracetam has been the only one out of the lot I've taken that didn't have other serious side-effects which created problems for me. Pentoxifylline is contra-indicated with other parts of my health profile, you could say.. =)
I've notice entirely no effect from any of this drugs with except of phenylpiracetam.
While I've used phenylpiracetam, I've noticed some effects: 1) I've got more physical endurance (I'm engaging in sports a lot) just from one doze of it; 2) My overall alertness arises; 3) My visual perception became more clear and vivid; 4) I was able to maintain focus for extended periods of time; 5) It was easy to wakeup and harder to sleep down earlier (my brain was like "so much ideas, need to think it all").
When I stop taking phenylpiracetam all of these effects gone away.
This is a fairly effective regimen, for me, for combating fatigue and maintaining focus. I simply keep a bottle of Suntheanine and another of Rhodiola Rosea at my desk and eat them with my morning water or tea. I haven't done any rigorous testing to prove to myself that these things are helping, but I am certainly convinced that they do.
I notice the texture of things more, and I constantly have a need to look at everything in my vicinity. It's not distracting however, and really helps with technical tasks.
