Recently my fiancee, 33 year old male, was diagnosed with ADD. I suspected for a few years that he had ADD, but knew that he needed to realize it as well so that he would seek treatment on his own. Six weeks ago he was prescribed Vyavanse, he wanted to save his job because he was so unfocused and now has done wonders for his job-he is focused and dedicated to working as much as needed to get the job done, he is organized, and really proving himself with his company however, it seems that other issues are coming to light. In the past he has had alcohol and cocaine addiction issues, he was actually sober for five years. A year ago he started doing the cocaine and alcohol thing again on a monthly basis, go out drink like a fish, do some coke and come home at 6AM. Recently, this has become a weekly occurrence. Every Friday night he is doing this now. I know he is not abusing the Vyvanse, but can the Vyvanse be increasing his want of the alcohol and the coke? The warnings for the drug say do not take this medicine if you have addiction issues. Is this because it could put you back into the addiction cycle with any drug, or because there is fear of abusing the vyvanse, or both? He doesn't seem to wind down at night and is sleeping only 5 or less hours a night. I am confused here and don't know what to do. My fiancee thinks that if he stops taking the medicine the quality of his work will diminish severly and he could potentially lose his job. He will not tell his therapist and doctor about his current usage of the alcohol and coke, although he did tell them initially that he had problems in the past with these. Also, can combining the Vyvanse, alcohol, and coke be dangerous for his health, specifically his heart? I would appreciate any thoughts and info you could provide.
