Report Is this hospital terrible or is it me? in Dysautonomia Discussion Posted July 1, 2020 Yes, they said I had ADHD as a child. I took ritalin. In my early 20's I was obsessed with this idea that my problems were ADHD / anxiety and I took a lot of psychotropic medications that, overall, caused more problems than they fixed. It is very strange. As a child I took a low dose of ritalin and I hated it - it killed my appetite but it did improve my school performance (although please note - long-term studies show amphetamines do not really improve performance). I tried it again in college, a higher dose of some amphetamine. And I think that the meds worsened my POTS-like issues (see what I did there?). My issues started in high school and got much better my freshman year of college (no meds), but worsened in my sophomore year when I was taking a higher dose of amphetamine, running cross-country, and definitely not getting enough sleep. What I think now is that a combination of stress, meds, running, poor sleep hygeine may have caused some damage when I was younger - and I had autonomic instability as a result. Perhaps it resolved as a result of improved sleep hygeine (and I got a device to treat my apnea), not taking meds, and laying off on the running. I hope I can get back into running now. The doctor said he thinks I should try to keep my cardiovascular fitness towards the peak end to reduce my susceptibility to orthostatic intolerance issues. I'll look at this research, Pistol. Thanks!
