BTDT with the meds. If you do eat the junk food you'll feel 10x more crappy.
I can't even handle the stuff or else I just get weirdly ill in spite of
cravings.  My almost-teenaged foster child likes regular Dr. Pepper which I
also love. I tried a sip and it didn't even taste right.

I've basically written off the cravings as a part of my day to day
existence - something that will be there and I just have to ignore.  My
"junk food" treat is a whole wheat tortilla with natural PB wrapped around a
banana or an occasional sf jello cup.

There's stuff that I have taken before, mostly antidepressants, the wreaked
havoc on my cravings.  So much so in fact, that it was more depressing to be
on them than off!

You need to take a hard look at the medications.  20 extra pounds can take
years off your life.  Are the meds worth it?

Sometimes there is an alternative medication without the same side effects.

Here is what you can do. Take a bite of it, chew it a while, realize
one of two things. 1) It is the best tasting thing around and you
couldn't possibly get enough of it or 2) It isn't really all that
great. Then spit it out, and get on with the diet. People are on diets
because they cannot control their appetites; therefore, you cannot
start eating stuff like that or you won't stop. That is what I have to
do occasionally. Often, I find the taste isn't as good as I remember
and that works just as well. I'm not about the screw up my diet for
ANYTHING or ANYBODY. Once you are on that bandwagon, you can get
through those cravings. dkw

BTDT...   Last fall I had this serious craving for oreo (double stuff).  I
then purchased some and put them in the cupboard.  They then stayed there
for a month before I finally opened them.   The thing was, as long as I had
them in the house and could eat them at any time, I was fine without having
them.
