Chirp,
Yeah to you for cutting out caffeine, alcohol, etc. Diet goes a long way. I believe that you should get your vitamins/minerals from food but I also think, as they have helped me, that supplementing can be benefical. You must educate yourself before you go to the drug store and start pulling bottles from the shelf. Here is what has helped me and I have been off meds over a year now and I feel great 95% of the time:
Vitamin E will help with heart palps, my completely stopped after 24 hours on vitamin E. You need to get the natural form, not synthetic. You can tell this by reading the label. The form should be d-alpha (natural), the synthetic form will read dl-alpha. Not much difference there, but a big difference in the way your body uses it. I would start low like 200iu twice a day and increase if you feel necessary to400iu twice a day. That is the level I am at now. One more benefit, in less than 2 weeks your skin and hair will look awesome!
B-complex plus extra Niacin(b3) and Thiamine(B1). I take this after dinner and I do not have issues with insomnia at all anymore. B vitamins must be taken together, not jut indiviually.
One good multi-vitamin a day. try different brands and see which one works with your body chemistry the best.
Vitamin C. I was taking 3,000 mil a day until I felt like I was saturated with it. Now I take 1,000 mil three times a week.
This has worked very well for me. Personally, I would stay away from amino acid supplements - that is just me.
A good website to get info from is DoctorYourself.com, they are not selling anything but provide some good research. I think they go a little overboard but you can decide what is right for you.
Good luck, I hope you get the good results I have.
