I have been taking one dose ashwagandha extract a day in AM for a long time. Very subtle results, maybe I take too little. Same with Valerian root. What are you taking for antidepressant/antianxiety? I need that long term, and the only thing that works well (even in very small doses) is SSRI or similar but i'm afraid of the "tardive dysphoria" thing.
Starting with ash dosing, I find that the effects are very much dose dependent and the reason I don't take a higher dose than I do is because it'll make me chill to the point I don't care about getting anything done and it'll make getting out of bed in the morning even harder than it is already for me.
The antidepressant I take is the tricyclic nortriptyline. It's a second generation TCA that was initially put into the market about 50 years ago so it's not going to have the sides of the older ones like amitryptiline or imipramine which are known to be rough. As far as sides and toxicity go, it's comparable to older SSRIs like luvoxetine or paroxetine and a good case could be made for it being more effective in severe depression.
What I like about it compared to escitalopram is that it doesn't cause emotional numbing, no sexual sides, and doesn't suck away the drive to do anything. In fact, for me it actually helps improve motivation just a little bit. It helps almost completely with depression but I'd say that by itself it probably relieves 60ish percent of excessive anxiety. Hence why I take ash, 5mg lithium orotate (microdose), and carry aniracetam with me so I have something to take on the fly if anxiety gets real bad. I don't take the ani regularly because it snuffs motivation in combination with the other things I take. I take these supps instead of the escitalopram with nortriptyline because the sides are so much more manageable.
However, I do have to deal with orthostatic hypotension and an elevated pulse rate. But I'd much rather deal with those. The sides during titration are very rough compared to escitalopram but for me they were more than worth it to put up with. Sides during titration that went away for me personally include lights looking blurry at night, insatiable appetite, daytime sedation, mild constipation, and I was less resilient against the hot humid Houston days in the summer regarding how long/much work I could do before succumbing to heat exhaustion.
