I decided to give piracetam a try about 3 weeks ago and since then I've taken it 6 different times. The first time I took 2400mg and 300mg of Alpha-GPC I became incredibly tense and then burned out about 30min later and needed to go to bed 4 hours early, and I did not see any cognitive benefits. Then, after the second time I decided I would take an attack-dose, so I took 4000mg with 300mg of alpha-GPC. This did the same thing, and it gave me TREACHEROUS nightmares. Before then, I hadn't had a nightmare in 6-7 years, and I wasn't going through any abnormal stress or emotional trauma. The next couple of doses did the same thing. I tried a micro-dose (200mg), and that made the sleepiness not-so-severe, but I still had to take a nap that day. And I took 2 doses (800mg) w/o choline, same effect. And, finally I took my last dose (yesterday) I took with 500mg of ALCAR and 400mg of piracetam (6 hours before I went to bed) and had another treacherous nightmare and woke up with night-sweats and was breathing heavily. I've given up on piracetam and haven't found anybody with a similar response as mine. (Also, every dose made me incredibly irritable)
So basically all piracetam does is give me incredible sleepiness/fatigue, nightmares, night sweats, no cognitive benefit, tension, and extreme irritability. And, all symptoms stay the same regardless of whether I take it with ALCAR and ALA, or Alpha-GPC. Larger dose makes symptoms worse.
