Hi Audryna
Contrary to what doctors believe,thal minors do have symptoms,i am a thal minor myself and i get tired easily,sleepy and sometimes even dizzy,i have headaches,and those clammy feelings and tingling sensations you are talking about,and if you'll read through the forum you'll find that most of the minors complain of same symptoms.
So what should you do,first confirm trough tests that you have thal minor,which i guess you have,then adding supplements like folic acid,wheat grass,B-Complex vitamins to your routine will help you tremendously,when i started taking B-Complex i felt a clear change in my energy level,but the break through came for me when i got checked my Vitamin D levels and i was very very low,i was advised to take Vitamin D shots and supplements,i have taken two shots till now and i am taking a vitamin D supplement daily,and let me tell that 60 to 70 % of my tiredness is gone,my leg cramps are gone,and i feel much much better,so you can request for Vitamin D testing too,unless you go out in sun a lot.
Hope this helps
