No, you will not be back to normal in 4 months...no way. You may feel OK, but that doesn't mean everything is back to normal on the inside...sorry, sad but true.
It can take a full year or more to fully recover from long cycles...I've talked about this in several threads on here in regards to me being on almost non stop for 3 years.
You would be best served giving your body a break...and no, everything is not hopeless.
You need a good PCT to start with...this will not fix everything but will make a good difference....and when I say you need a good PCT, you need to run one that is longer and more potent than the average PCT.
I'd start the PCT with 1000iu of HCG/ed for 10 straight days. After that begin clomid. Start with 100mg/ed for 2wks. After that drop down to 50mg/ed for 1wk but add in 40mg/ed of nolva. Some will scoff at this saying both are not necessary...I say your PCT will be a far greater success if you do it this way. After your wk of clomid and nolva, drop the clomid and use just nolva. 1 wk at 40mg/ed, next wk 30mg/ed, last wk 20mg/ed...then off everything.
If you're worried about muscle loss you may need to up your calories a bit...if you stay naturally lean this won't be a big deal. However, if you put on fat easily it will be a problem, especially while you're still fresh in the coming off stages. If this is the case you will need to drop the carb intake considerably...yes you will lose some size, but if you keep calories right at or slightly above maintenance you will be fine...learn to utilize fats in your diet more efficiently at this point.
