Free Acid vs Sodium Potency & Abuse Potential?

So I've been taking sodium (50mg doses a few times a week), for the last few months. At one point I was taking high doses, but stopped because I was scared of getting withdrawals.

So A few weeks ago, I received some free acid from New Mind, and started taking it instead of the sodium. And I have a few questions because it seems like a different drug altogether than the sodium.

I've read on here from people that they take roughly twice as much free acid to equal sodium potency. However, I'm finding that for me, it's more like 3-5 times as much, or more. And even at those doses, it's nowhere near as heavy or strong as a 50mg sodium dose.

A 50mg sodium dose will hit me pretty good and fast. However, I've found that I have to take at least 150-250mg of the free acid for it to do anything.

What's odd is that I actually prefer the feeling of free acid when it works. Even at high doses, it's subtle, but it boosts my mood without giving me the downer opiate feeling that the sodium gives me. I really really like it, it's got some very good anti depressant properties that I don't get with the sodium. I just have to take quite a bit to feel anything. I don't get much from sulfate either.

Another thing I've noticed is that the free acid is short acting, almost as short as the sodium. However, I've been reading reports from people on here that it's supposed to last much longer, so I'm a bit confused. Sometimes I feel like it lasts 1-2 hours, and very rarely it will last longer but that's rare. I have a few different batches of it, so I know I didn't get a weird batch.

Also, what is the abuse / withdrawal potential if I only take free acid and stop sodium altogether? When I was taking sodium, I did not take it every day (maybe 4-5 days a week) and never experienced withdrawals. But I've been taking the free acid for about 3 weeks now every day. But I never took the sodium every day for this long. I'll take anywhere from 200mg to 800mg of the free acid daily (although the high days are not very frequent, it's usually closer to 200-300mg).

I haven't felt any withdrawal symptoms yet. At least nothing too bad. I decided not to take any today, so it's been roughly 15 hours or so since my last dose of 200mg and other than some very very mild anxiety (I have anxiety anyway) I feel ok. Is free acid just not addictive?

I read a lot of horror stories on sodium withdrawals but I've never read about anyone withdrawing from free acid, at least not in the same severity as sodium. I've even read reports that it's not even active (although I do feel something for sure).

Just trying to get a handle on this as there seems to be very limited info on free acid.
