Personally, I abstain from alcohol because I am already off balance as it is. If you are taking any medications including OTC meds, you should read the label to see if alcohol is ill advised.
RRMS to SPMS transition is typically a decision your MS Specialist (neurologist) would make. If you visit websites which discuss different MS types, they usually provide a line graph to show you the differences. Some MSers may never move beyond RRMS and some MSers may experience remission which can last for many years (no guarantee).
I too have a temperature window where I am ok. I have learned what my upper and lower limits are and try to avoid these. For example, when the temperature drops below 52 F (11.11 C) I know I will experience numb hands that can feel quite painful and my head will also feel a deep stabbing cold. I will wear gloves and a sock cap, often indoors too. It may be from autumn to early spring for me to wear these.
In the summer months I soak my hands and feet in ice cold water and this alleviates my numbness or tingling much of the time.
For some MSers, they may experience a lasting condition, such as numbness, which does not go away. This can happen regardless of type of MS.
Though females outnumber male MSers, males are the ones who most often develop into progressive MS, but again, this is purely statistics and no guarantee. In studies involving men with MS, male gender was predictive of a shorter time period before an assistive walking device was required. For example, men were quicker to need devices such as canes after diagnosis. I went 20 years before I needed a cane/crutches/power chair.....
The question of "normal", I think, is up to the MSer. What is "normal" nowadays for me would be a terrible rotten day for another MSer. I have redefined what is normal for me many times over 35 years because my benchmark changes.
