Loads of them. Same questions get asked regularly so it would help reading previous threads. Or ask, that is what support forums are for!
Off the top of my head some things regularly asked -
There are 5 doses in each pen, buy some syringes to get the 5th
Staying on the lowest dose makes sense if it is giving you want you need, but buying the 5mg pen as your 2nd pen and taking 2.5mg if it works for you also makes sense so you have the flexibility. Some providers push you to move up, you don't have to!
Track calories in the beginning to make sure you are eating enough and to get a base line for portion sizes.
Eat protein at every meal if you can
Drink water - work up to at least 2L
Weigh daily/weekly/monthly - doesn't matter which one you choose to do that suits you
Take measurements / recalculate your TDEE at the start of each pen
Vitamins - some do / some don't because they get enough through diet
Exercise is important to retain muscle. Walking is good and some strength training.
Ask your local pharmacy if you are struggling with constipation, D&V etc they can prescribe something
Hair loss is common with rapid weightloss
Some people lose slower than others, they are not doing anything wrong
Read the two patient leaflets! - it contains all the information you need for changing injection day, issues with oral contraception, how to store used/unused pens, what to do if you miss a dose etc
Don't post your codes on this board. There is a promos board for WLI
And lots more.........
