I have ADHD and to be honest I think being on meds is way better- I take dexedrine and I went off of it for 4 years-- it was a bad decision. I went off Effexor as well and I took up yoga but I just wasn't functioning. ADHD is a serious biological deficit: poor planning skills; troubles focusing; impulsivity; hyperactivity or not being able to get going- period are just some of the issues. Personally, I think PSTD would get worse because not only are you dealing with all of the grief etc., of PSTD you would also be dealing with the issues related to ADHD. Dexedrine grounds me--period. It helps me focus, concentrate, plan, manage things. Its no ta panacea but without it I am either running all of the time; or sitting on my couch crying. There doesn't seem to be an in between! Peace.
