I've taken both, but in different strengths so it's not really comparing apples to apples I guess. However, I took the deca one this last time, low dosage. 4 mg twice a day/3 days, then kept halving the dosage until 12 days were up. After just the first dose, my hearing was almost back to normal...unbelievable. However, I could tell it was getting worse as the 12 days were coming up. Now, I'm not as bad as I was be fore, but I'm not that great. Hearing is distorted.
I didn't have any bad side effects those two weeks other than not sleeping well. I took a Sonata at night and got at least 5-6 hours straight sleep, then I'd be up for an hour or so, reading a really boring book, then would dose for another 60-90 minutes before up for the day.
No weight gain, no intense hunger. I did have a lot of energy. I was coming home after work polishing the silver tea set, taking everything out of my china cabinet and polishing it, taking the vacuum to curtains. Sewing things, fixing things that I've let go for months/year. I got so much stuff done in those two weeks. LOL! I almost miss that.
