I do have mild symptoms of ADD...its more mental fatigue when i study than anything else. If I exercise early the morning then I'm usually able to study effectively the rest of the day.
Exercise is important. I try to excercise, either cardio or brisk walking, every morning. This helps almost as much as the medication.
I haven't been taking Ritalin for regular studying but only in the last week for reviewing. However, I've noticed during the actual exam simulations, Ritalin actually makes me do worse....sort of like unnecessary test anxiety. It also gives me awful insomnia. I think I'll avoid taking it for the actual exam and just exercise that morning.
Definitely skip the Ritalin for your exam. Ritalin
can cause anxiety. Anecdotal evidence is that anxiety caused by Ritalin is more likely among those who don't actually have ADHD. For those of us with bona-fide ADHD, Ritalin often reduces anxiety and gives us a "more calm" feeling when under stress. It certainly works this way for me.
Because Ritalin is a stimulant, it must be taken early in the day, or it WILL cause insomnia. If using fast-acting Ritalin, it is typical to take 2 doses, one at breakfast, the other at lunch. I myself take Concerta, which is time-released. One Concerta taken at breakfast lasts all day. By evening, it wears off (slowly). I sleep equally well with or without Concerta.
I've been taking Ashwaganda, Bacopa, a high quality Fish Oil, Rhodiola Rosea, and Ginko biloba for the past few months. I added ALCAR to my stack a couple weeks ago. My memory and mood has definitely improved on these. The Ritalin did help for review over the past week but I don't think the anxiety and insomnia I get from it is worth it
+1 on the fish oil and ALCAR. Nearly everyone should supplement these, even if they don't have ADHD. I find that it is best to take these before breakfast
+1 on the ashwaghanda too. I think ashwaghanda is great. I take it in the evening about 1/2 hour before bed. Ashwaghanda is relaxing. Some people say it is even sedating.
I have some Rhodiola but haven't tried it yet. Others on imminst have contraindicated Rhodiola with Ritalin, saying it causes excessive stimulation and anxiety, maybe even hypomania. These folks recommend taking Rhodiola only on days where you don't take Ritalin. Rhodiola is stimulating, so take it early in the day if you use it
Gingko I'm not so sure about. I've tried it on and off, but never noticed any substantial effects.
If you are able to, I recommend seeing a psychriatist for an actual diagnosis of your ADHD. It's also a good idea to get blood tests, especiallly for thyroid. Hypothyroid or other endocrine and hormone problems can cause mental fatigue, brain fog, low energy, and many other symptoms which are similar to ADHD. After a diagnosis of ADHD has been confirmed, many psychiatrists (in the USA at least) will treat the ADHD with a combination of stimulants (often Ritalin or Adderall), and an SSRI (I take sertraline [Zoloft]). I'm not entirely sure about the scientific reasons for using the SSRI, but sertraline is known to be anti-anxiety among other things. Diagnosis and treatment of ADHD seems to vary a lot from country to country. If you aren't in the USA, there may be substantial differences in the way ADHD is both diagnosed and treated.
