I had them in March this year, I’ve only had IV ones before that. They taste disgusting and the taste lingers for half the day so I got through lots of mints.
They make me feel jittery and hyper - I could only sleep for a few hours at night and I was more chatty than ever. I felt exuberant at a time when I should have been feeling down. I was up one night decorating a cake until 1am and still only slept for 2-3 hours! I also had a little facial flushing.
The following week when I had finished them, all I wanted to do was sleep and cry (I call it the weepy and sleepy stage now!)
However, they were worth it for me because at the start of the week I could only shuffle along and by the end of the week my walking had eased off. I still tired very quickly and it was still a long slog back to walking properly but they certainly kick-started my recovery.
I would only take them for severe relapses though due to the side effects. Three months later my GP offered me them again when my other leg played up but I didn’t want them (a) because I wasn’t convinced it was a relapse, I think I was in denial as it was very similar symptoms and (b) because all I had asked for was a referral to physio.
