Your GP has given you a drug which is known to work

…….. if you mix you will NOT know which does/not work. Herbals sometimes work for a short while and there's nothing wrong with the placebo effect. I was SO worried about taking stuff but it was that or not survive

If you have had over 8 hours between medication/herbals you should be OK with Valium - 2mg is not a big dose and you should find it relaxes you.
If you are unhappy with what your GP has suggested, go to a pharmacist 2-morrow for a chat as to what will work the quickest? and he/she will tell you what you can take, with what and when ……
Only you can decide what exactly you want to take. None of us can stop the side-effects that might happen ………. which is why keeping a chart can be useful. Valium can be quick acting so having a warm bath, a cuppa and into bed before taking the 1st dose may enable you to sleep. You may wake in the night to see if you've been asleep

…….. that happens to me!
