My son recently went through detox - prior to that he was snorting 5 or 6 30 mg. oxycontin's a day for about 2 1/2 years. He got out of detox 2 1/2 weeks ago and so far is 3 weeks clean. However, he is having a lot of problems with anxiety, stating his mind won't "slow down." He is having depression also. Are there any over-the-counter supplements that can help? We have read about 5-HTP and L Tyrosine. Has anybody tried these for the anxiety and depression after detox?
