Just wanted to understand why certain things hit me very hard while they don't affect her at all.

I have a couple of physical conditions and I'm trying recommended medications. I took one 10mg dose this morning, and have been in and out of deep, heavy sleep all day - it is now 12 hours after ingesting and have just woken from another 3 hour sleep.

My partner took the same dose and has not shown any tiredness in this time. The same usually goes when we both take a heavy painkiller with codeine. I will be out of consciousness for 10-12 hours and she won't feel affected unless she take two or three more.

I'm told I should feel lucky that these things work so well on me, but I'm curious if it could be that something in me is not functioning properly and could give me a better quality of life if I get it fixed?

Thankyou
