Light or no flavor taste at my "modded" Ego-T.

[Arizon]

Hello.I've been visiting this forum for a few weeks to solve my problems..But now,I couldn't find anything to help me so I must ask for help.I have an Ego-T Top and Ego-C bottom e-cig (The battery is Ego-T and the rest is Ego-c,sorry I'm very new so please use simple terms if you can).

So,everything went good for 2 weeks aprox. but for the last 2 days,I started having problems with the flavor of any e-juice i used.I thought the problem was the atty so I changed it..nothing happened.Anyways,Some of my friends tried my e-cig and it was fine,but as I said the last 2-3 days,it started to have a bad taste(their opinion).I didn't and I don't feel a bad taste when I use it,but I feel like there is no taste at all..or a very light one.I cleaned the e-cig extremely well,even the tank with hot water,but still the same.I saw in few posts that maybe my "taste buds" are tricking me.Then I wondered why my friends are telling me that it tastes horrible?

So...Intense cleaning,changed flavors,changed atty..and still no results...Also,Bad taste-light/no taste?..What's happening?

P.S: (I'm not a good english speakersorry for that)
