TLDR: Took some speed, didn't feel anything apart from cristal clear mind and no need to rest.

Context: Have never tried speed before, have never tried cocaine before. Location: Berlin, Germany. Got 7g, washed with acetone - 3.2g left.

I decided to try speed at the club since I heard great things: energy, euphoria etc. I tested, washed (7g, after washing 3.2g) and portioned the powder into 40mg packs. I read 30-40mg would be a normal portion if snorting (Thinking now: If the purity is 30% and after the wash it may have increased so probably 40mg is very low?).

At the club I took 2 packs of 40mg washed speed and a little bit of ketamine because people said it's a good combo. I snorted the first 40mg. 20min later - nothing. I snorted another 40mg. 20min later, still nothing. So I started taking K, so at least to have some fun.

Unfortunately, I had very little K and after 2 hours I felt super sober and the party was not the best. I decided to go home but then I just stopped at DJ and started moving and I realised that I cannot stop moving, I somehow have a very clear mind and energy to dance and I don't want to stop dancing. It was very weird state of mind. One hour later, dancing non stop and being absolutely sober in my mind, I decided to go home since I felt that I don't like the music thou my body wanted to dance.

Anyway, when I got home, I realised that I am very very calm, my mind is TOO clear and I am not too tired and I may have issues falling asleep. Somehow I didn't have big issues falling asleep and I had a very good time sleeping.

Questions: Does speed give euphoria or high of some sort? Or does it just kill the feeling of tiredness and you need to combine it with e.g. K to get a bit high? Can it be that I took a very small dosage and I felt just a few effects?
