I've been taking 40mg/day perc prescribed for over a year now. The high was very intense and enjoyable in the beginning. It's tapered off considerably. I have to take nearly double to achieve the same result. I'm guessing this is due to serotonin decrease. I am not wanting to increase the dosage. Is there a supplement that I can take to get the intensity back? I'd prefer not to quit taking it because I get sick if I don't but I'm not sure of any other way to get my tolerance back down. I've read a possible solution would be to plug it but I feel like that would only be a temporary fix.....I'm also not sure how to do it.
