Report Am I Working My Body Too Much? in Dysautonomia Discussion Posted February 10, 2011 I can't answer questions about the adderall. I would talk to your doc about whether mixing what is probably still in your system with coffee is ok.As for your experience before, during, and after exercise I would have to say that it is the same thing I experience. I generally handle working out fairly well and as long as I don't push it like crazy I feel great during my workout (If I overdo it I can end up pretty dizzy at the end and after my workout). I have an hour with give or take where I feel great (more alert, less dizzy, less brainfog). Then that wears off and the dizziness returns and I will be way more tired/fatigued. On nights I work out (I hit the gym in the late afternoon before I head home, usually 3:30-4:30) I tend to get home, showered, and then I crash on the bed and want to sleep-- which is very unusual for me during the day, and annoying now that I have started midodrene. Coffee will get me going, and can sometimes help even with the dizziness but I usually have to have between 2-3 cups to get the vasocostriction and feel alive. Obviously, that isn't the best at 5 p.m. and can cause some other symptoms like shaking and flushing from the caffeine.
