Any alternative way to increase my dopamine without taking some kind of anti-depressant? I take Adderol which doesn't help much in the libido
area - in fact in my experience it's the anti-libido drug. It would be nice to raise my dopamine and possibly solve 2 problems with one solution.
There's no way of knowing which hormone, neurotransmitter, or other chemical is causing the favorable effect. Grapefruit juice inhibits the breakdown of hormones etc. in the liver, thereby extending their half-life. Now as the half-lives of these hormones/chemicals are extended, the body will usually cut back on the production of these hormones/chemicals since there is sufficient in circulation. The only time the body may not cut back, is if it deems that there is "still room" for more of a particular hormone/chemical. Such an example would be in the case of testosterone. Your body may be producing testosterone but maybe less than what the body deems "okay" before switching off. In such a case it is possible that testosterone will be allowed to accumulate before being switched to lower production. BTW, licorice will cause the same effect, except that licorice also acts as an estrogen, so it is bad for men to take.
