There's a lot of posts in this forum about licorice. Those may be a good resource for you.

I got myself a bottle of Nature's Way "Licorice Root" — 100 capsules with 450mg powdered licorice root per capsule.

I started out with 1-3 capsules daily and found that as much as 1 capsule daily was enough to give me headaches. I'm pretty sure it was the licorice. I'm now at 1 capsule every 2 days and that seems to work without side effect.

I've been doing well for a while and I think one of the major contributors has been licorice. I decided to back off of it considering it affects corticosteroids and you don't want to take corticosteroid-affecting substances for too long. I switched down to 1 capsule every 3 days. At roughly the same time I've been taking more stimulants (caffeine, chocolate), so I can't disentangle the factors, but I note that I have not been doing as well during this period.

When used with corticoid treatment, glycyrrhizin interferes with 5 beta-reductase breakdown of corticosteroids, thus prolonging its biological half-life. When someone discontinues the use of licorice after consuming it over a long period of time, they should withdraw from it slowly, unless they are discontinuing it due to side effects. In the case of dangerous side effects, they should immediately withdraw from its use.

I'd been using licorice for three months.

I did not start taking Licorice until about 10 months into my recovery program, after regaining substantial adrenal reseve capacity.

I first started taking Licorice root powder in capsules, and I got a great energizing & stamina increasing effect from it. It let me stay active about twice as many hours in the day without fatigue... seemed to brighten colors and mood... and it left me a little wired and hard to sleep at night.

I took a day off of licorice after being on it for two weeks daily, and I crashed very hard due to an unexpected stressor that normally would not have caused such a big crash. I think going off it suddenly lowered my cortisol level or the adrenals became slightly "addicted" to it.

Like Marie64, now I only use licorice "as needed" - when I have a long workday or weekend activity that needs extra energy.

A great tip is to make licorice root tea and sip it slowly throughout the day, as needed. (STASH Licorice tea is awesome, but any kind of natural root in a teabag is fine). The tea seems to be more gentle and smooth for me than raw root... probably weaker... and less likely to cause crashes.

Dr. Lam suggests taking licorice no more than 5 days on, 2 days off... so you don't get addicted. And not taking it until you are stronger and less crash prone.

I personally avoid things that will cause my body to become addicted, or that will become more of a crutch than a contributor for actually healing. I want my body to make its own hormones, cortisol, etc. I know that sometimes certain things are absolutely needed, but I only will go that route if there is no other choice.

Every time I take licorice, I feel stimulated and very energetic, but I feel that it is a false energy and is not a natural feeling. I've read somewhere that Chinese licorice is much better than American licorice.
