Advice would be lovely

Hi everyone, I’d like to start this off by saying that I had a phone consult with my GP today and he told me to persist with the medication, and I will, but I would love to know if this has happened to you, or something similar.

yesterday I was put on Dexamphetamine for adhd, I was diagnosed last year at 33, but tried to cope with the knowledge and diet/exercise changes, except that I didn’t end up changing anything because thats one of my biggest issues, is I am unable to do anything, I’m not sure if that makes sense, I cannot stick to anything, I have the best of intentions but never end up doing what I want to do, I feel constantly overwhelmed and as though I am too busy, even when I am not doing anything at all. that’s besides the point.

so yesterday, as per drs recommendations, I started 2.5mg at lunch time, i kept a journal and it went something like this: before taking the tablet i was hyperactive, i get very hyper if im talking to people, not sure if its because im lonely or just a usual adhd trait, after taking the tablet i calmed down almost immediately, but not in a good “I have a clear head” kind of way, rather in a “i feel a bit dizzy, my head feels like my brain fog is worse than ever, i cannot think for the life of me”, i then started to feel miserable, really low, I even dropped out of the courses I was doing at uni and told my husband that it’s over for me, my brain just does not work anymore.

this morning I woke with the worlds worst headache and was still miserable, I took another 2.5mg as per drs orders, and that was that, I was so lethargic that I couldn’t get any housework done, when I normally race around and have all the necessary chores done first thing so that I can study all day. Chores got done hours later, and it felt like I was dragging my feet the whole time. I rang the dr and told him everything, he said to persist with the medication, I took my child to the shops and realised that I don’t believe I’m overly safe to be driving as I was unable to concentrate as well as I would have liked and my brain was just mush. I haven’t been able to enjoy myself, even when out, I feel like all joy has been sapped away from me. I took another 2.5mg at midday as per drs orders, hoping that maybe im just being silly and it’s all in my head, but now (an hour ish later) I just want to go to sleep, I’m that exhausted and weak, I have no focus, no ability to do anything other than sit here on my phone.

has anyone experienced this? Does it get better? i really don’t want to feel like this, and honestly would rather be the lunatic I was rushing around and buggering up all the time, than to feel like this.

sorry for the long post
