Thanks for the encouragement and advice Romanjade! I will look into your recommendations. I have taken 5 Hour Energy a couple of times before. It’s been a while & I don’t really recall how it worked for me. I seem to remember that it made me sweaty, but that’s tolerable and MUCH BETTER than being irritable with Co-workers or crying!! Any particular brand on the L-tyrosine or B-12 that works for you?
