I’ve tried it (many years ago, and before MS was suspected).
I’m sorry what I have to say won’t help you, but not the one for me, I’m afraid.
Nothing to do with weight gain OR libido, but had very abnormal sleep patterns and horrific nightmares - train crashes, bloody murders, terrorist attacks - you name it. Grew afraid to go to sleep.
Reported this, initially to be told: “But that’s your depression, isn’t it?”
I was no stranger to depression, having suffered for years (or was it MS fatigue all the time?). But had never, ever, suffered nightmares on this scale before - like Hammer Horror, every night.
Also very difficult withdrawal from it, with flu’-like symptoms commencing if I was as little as one hour late with a tablet. You can imagine how great that is, if you’re a little bit late back from somewhere, and haven’t put one in your handbag.
It has a very short half-life, which means it doesn’t stay in the body to tide you over if you’re late, or forget one. You effectively have the symptoms of cold turkey immediately. For the same reason, the recommended tapering regime for coming off, of switching to alternate days, then every third day, doesn’t work either, because you don’t have enough residual drug left in your body to see you through the days you don’t take one.
I appreciate not everyone has these problems - at least, I can only assume not, or why the heck is it still being prescribed?
But I have to be honest, and report a bad experience. I wish I could tell you: “Yes, it really helped, go for it!”
Sadly, my experience means I cannot in all good conscience recommend it, even if there’s a chance I was very unlucky, and most people are side-effect free. At least if you decide to try, and notice any side-effects, don’t get fobbed off with: “But that’s your depression, isn’t it?”
As soon as I managed to quit, the nightmares stopped almost instantly. Coincidence? If they started with the tablets, and stopped with the tablets, nobody can convince me so.
