Number. 1 lesson, don't listen to your AME. Most AME's are not pilots. Most can care less what there decision entails to a pilot when they medically disqualify you. There is one in Colorado Springs I use and if you want to PM me I will get you his information. He is also a Senior Flight Surgeon with the Air Force Reserve. He's a good guy and will do what he can to help. There is no reason you have to discontinue your flight training while getting the medical sorted out. I know what your talking about and exactly how you feel. At the time i did my medical i was taking welIbutrin to quit smoking. I kept taking it because I was just in a better mood then I was before. I found i was not always arguing, or angry all the time. Just a hint (St. Johns Wart is a natural supplement and does the same thing but because it is not a drug FAA does not consider it a medication ) Of course i was denied because wellbutrin was an antidepresent. At the time any use of antidepressants were automatic denial and no special issuance could be given . About two weeks after receiving the denial letter, I had my doctor write a letter that I was no longer on the medication and that there were no adverse effects and that I was being monitored regularly. I included the doctors letter and other things the FAA wanted in a packet and wrote a letter requesting consideration for a special issuance and 45 days later I received my 3rd class medical.
It is frustrating, but don't give up. You can still fly and take lessons without a medical, you just can't solo. So, if flying is what you want to do continue your lessons on the ground and in the air. Talk to your doctor to see if there is something that can work that is not considered a prescription medication and keep your head up. So, you may not solo as quick as you wanted to, you can spend the time with an instructor and learn more before you do solo.
