I have just recently started taking a combination of vitamins that gives me a strong euphoric feeling, I feel AMAZING on it! If anyone here would be willing to try it I would like to know if it works on other people too. The combo is: vitamin B complex (B-Supreme on the internet), L-Tyrosine, L-Tryptophan, Methylfolate (L-5-MTHF on the internet), Vitamin D, Vitamin K (MK-7 on the internet), and vitamin B12. It is harmless with no side effects!
I have found vitamin B Complex helps me a lot as well.
I am going to try L-tyrosine soon as I have read that it can help with motivation.
I am really pleased that you have found a good combination.
