ADD/ADHD...

*No judgment please*

I have had severe ADD my entire life and have been on Adderall for several years (previously I was on Vyvanse but when I switched jobs a few years ago, my insurance didn't wanna pay for it, so I was forced to switch to Adderall). I am also a daily, multiple cup coffee drinker. I've been trying to be wean myself off of my Adderall and cut back on the coffee, but unfortunately have severe fatigue and extreme difficulty concentrating. I know that when I get pregnant, the fatigue will be more extreme, but I'm afraid to take my meds because of how they may effect the baby. Has anyone else had this problem? If so how did you manage? Thanks in advance!
