I've been plagued by emotion..

Phenibut (Beta-Phenyl GABA), I used to take every day, increasing and decreasing from 0mg to 1000mg (By 100mg a day) - It caused ups (Hypomania and ecstasy) and downs (Suicidal apathy), every couple of days. I don't recommend it at all, very addictive for many.

I was given pregabalin (3-isobutyl GABA) by my psychiatrist (For the phenibut use), which stopped the need for phenibut completely (I still take it sometimes cuz it's a good emergency euphoriant), but just 75mg of pregabalin a day, it balances my mood very well (It's a low dose - Since 150mg makes me feel dumb and spacey - but 75mg is all I need). If you were to take pregabalin, know that the withdrawal is AWFUL for people, they can't get off.

Gabapentin is a better option.. Helps with anxiety, mood.. For me, it can cause a type of hypomania that's similar to phenibut, but less clear. People also use gabapentin to get off of phenibut (Cuz it works very similarly to pregabalin), easier to withdraw from. People find that recreational use of gabapentin isn't as good as pregabalin, and some prefer gabapentin (For reference). In the beginning, you'd feel really relaxed and calm, then the therapeutic effects last once you increase the dose. I can't take it because it gives me heart palps (When pregabalin is supposed to be worse for that).

Topamax was given to me (At 200mg) for addiction, and my outpatient psychiatrist took me off of it and he said "This medication can make people lose 20 IQ points when they're on it".

Idk much about other mood stabilizers. I was put on lamotrigine earlier this year, and I felt like I was on bath salts, but it increases feel good chems (Good for depression) and lowers glutamate (Good for mania).

But all I'm saying could be nonsense.
