    • Started taking during the day before the gym. Works well. Can’t say how much it’s impacting my sleep. I guess I’ll know when I stop taking it in a month or two. Will report back with any side effects otherwise I’ll write a end report after ceccasion. 
    • Still going strong. It seems with every few days on this I become more human again. I’ve had bursts of enjoying music. Feeling like life is beautiful again. Some anxiety that I’ve wasted so much time being sick... but hey what are you going to do?   still highly recommend the use of this peptide. 
    • Whelp I took the plunge. Didn’t notice really any effects. I felt a little uncomfortable physically later in the evening. I think I’ll do 500mg twice daily and see how that goes. Apparently this stuff helps repair dysfunctional nmda receptors and that’s what I’m looking for as I believe oxiracetam really did a number on mine.   i read one report on here about a user having a bad reaction. Jess I think. She also got relief from keppra. Since Sarcosine definitely impact ampa function, and I’ve noticed those who benefit from keppra are those with SEVERELY hyperactive ampa receptor functioning, I believe this explains her reaction. I have no way to tell for sure if Jess was suffering from increased ampa atomization, but the majority of my hppd was caused of overuse of coluracetam which is a highly poten ampa receptor HACUe. My symptoms were 100 percent in line with every keppra success story in terms of the symptoms they were suffering from (it’s a very distinct kind of hopelessness one learns to identify). These people tend to have those life changing moments on keppra without the typical side effects one would expect from a med like that. I’ve tried keppra twice—once with very high cholinergic functioning that was causing crippling depression and suicidal ideation. It worked like a charm. Cognition improves along with mood. Then I tried it again when I had normal/sub par cholinergic functioning. Side effects. Depression. Lethargy. Memory issues. Interesting to think about no?   I was able to knock down my HACU by withdrawing from benzos and keppra very quickly (not a fun experience; I don’t recommend it but it worked). So if you are a responded to keppra, stay away from things that enhance ampa until that’s under control.    Anyway a litlle sidetracked. Will report back on the Sarcosine.
