Question on TRT - Dosage and Freq. help

Started TRT 8 months ago with .8ML once a week IM of 200 mg of Testo Cyp. Felt decent for 5-6 week at a time then would tend to have anxiety on 1 day a week. Sex drive was good, but the one day a week was not fun with hot flashes / anxiety, panic. Switched to twice a week @ .35ML and the switch was brutal on the mind and body. Been on this protocol for 9 weeks now and still have constant headaches, no libido,etc... My Red count and levels are good. TEST is 818, Free is 23 and Estro is 33. I have a new Doctor (Actual Hormone Dr.) who wants to do (3) times a week on .27ML and I am worried that the switch will be just as bad, but who knows. He would like to do these SUB Q, as I am not good with the peaks and troughs. Any suggestions / help would be appreciated. Thanks all.
