Side effects when starting Ritalin??

When i was on it, would get headaches anytime I quit for a few days, and anytime I started back.  After about 1 to 2 weeks these taperred off.

Don't know about the pain threshold, for I was always like that since my nech injury.

I was taking 80 mg a day, 40 twice a day, and my heart rate stayed high (as in sitting at rest would be 105 bpm), I was always hot, and constantly hungry, but could focus.  Yes we tried other things, and smaller doses, didn't work.

Got off meds once I got out of college, basicly to save my heart since heart problems run in my family. 

Hello,

Started on Ritalin this saturday..3 x 10 mg a day.
I am having lots of side effects.
I feel tired after the second pill, get headaches, I feel floaty, my heartrate goes up by 20 beats or so after the least bit of strain (like coughing even), I feel warm all day, my metabolism seems to go faster, and my pain-treshhold has gone up.
Yesterday I scratched my arm and it was a bit too hard I believe because now I have 2 6 inch scratches on my arm...So nice...At least they didn't bleed but it's like I was on ecstasy again, the feeling you get after 2 days partying...and I don't like it.
Phoned my MH doc (who prescribed the Ritalin in the first place) about it, but only got his secretary (as usual). Hope the b*stard calls back this time because I phoned him 3 times last week and no response...And he said he was there for me, or at least within 24 hrs..
I need his report on my ADHD for a programme for work (reintegration stuff) and I need it NOW.
Are all doctors like this? Unreachable when you need them???

Sorry for the rant but I had to tell it somewhere..
